=== SciGRID ===

[http://scigrid.de/ SciGRID] is a project which started in 2014 and will be running for three years. The aim of SciGRID is to develop an open and free model of the European transmission network based on data from the [http://www.openstreetmap.org/ OpenStreetMap]. It is carried out by [http://www.next-energy.de/ NEXT ENERGY - EWE Research Centre for Energy Technology], an independent non-profit institute at the University of Oldenburg, Germany, and funded by the [https://www.bmbf.de/ German Ministry of Education and Research],  and the initiative [http://forschung-stromnetze.info/ Zukunftsfähige Stromnetze].

An unofficial, post-processed version of SciGRID version 0.2 for Germany with attached load, generation and transformers is available as a [https://github.com/FRESNA/PyPSA/tree/master/examples/scigrid-de PyPSA example], see also [http://pypsa.org/index.html#screenshots-and-example-jupyter-ipython-notebooks screenshots]. 

=== GridKit European Dataset ===

[https://github.com/bdw/GridKit GridKit] uses spatial and topological analysis to transform map objects from [http://www.openstreetmap.org/ OpenStreetMap] into a network model of the electric power system. It has been developed in the context of the [http://scigrid.de/ SciGRID] project at the [http://www.next-energy.de/ NEXT ENERGY - EWE Research Centre for Energy Technology], to investigate the possibility of 'heuristic' analysis to augment the route-based analysis used in [http://scigrid.de/ SciGRID]. This has been implemented as a series of scripts for the PostgreSQL database using the PostGIS spatial extensions.

[https://zenodo.org/record/47317 Data extracts] are provided for Europe and North America in a similar CSV format to [http://scigrid.de/ SciGRID].

 

=== osmTGmod Model ===

[https://github.com/maltesc/osmTGmod osmTGmod] is a load-flow model of the German transmission-gird, based on the free geo-database [http://www.openstreetmap.org/ OpenStreetMap] (OSM). The model, respectively the heuristic abstraction process employs a PostgreSQL-database extended by PostGIS. The key part of the abstraction process is implemented in SQL and ProstgreSQL's procedural language pl/pgSQL. The abstraction and all additional modules are controlled by a Python-environment.

 

=== Bialek European Model ===

The 2nd version of the [http://www.powerworld.com/knowledge-base/updated-and-validated-power-flow-model-of-the-main-continental-european-transmission-network Bialek European Model] is downloadable as an Excel file and in the format of the proprietary modelling software [http://www.powerworld.com/ PowerWorld]. The model covers voltages from 110 kV (a single line in the Balkans) up to 380 kV. It is released under a Public Domain Dedication. 

The 1st version was released in 2002-2004 and is no longer available (see [http://web.archive.org/web/20100525115039/http://www.see.ed.ac.uk/~jbialek/Europe_load_flow/ Archive mirror]). The 1st version did not contain the Balkans region.

The methodology and validation for the 1st version of the model can be found in the paper [http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=1425573 Approximate model of European interconnected system as a benchmark system to study effects of cross-border trades] by Zhou and Bialek, 2005.

The model contains the impedances and number of circuits of each line, but not the length (which can in principle be determined from the impedance and number of circuits, given standard line parameters). Only cross-border lines are assigned thermal capacities.

There is currently no coordinate dataset for the buses. The PowerWorld file contains spatial data, but in an unknown projection. The [https://github.com/nworbmot/georef-bialek/ georef-bialek github project] is an attempt to fix this; there is also a [https://zenodo.org/record/35177 geo-referenced version] from Tue Vissing Jensen.

=== DIW ELMOD-DE open model of Germany ===

[http://www.diw.de/de/diw_01.c.528493.de/forschung_beratung/nachhaltigkeit/umwelt/verkehr/energie/modelle/elmod.html#ELMOD-DE ELMOD-DE] is an open model of the German electricity system developed at DIW and TU Berlin, which includes both a model of the high voltage transmission network, power plants, hourly load and weather data for the year 2012 and GAMS code to run linear optimisation simulations. It contains 438 geo-referenced network nodes and 697 transmission lines at 380 kV and 220 kV. Transformers are not modelled but per unit line series impedances are adjusted to the voltage level.

The model includes 47 pages of documentation.

The transmission data was, according to the documentation, derived from the VDE and TSO maps and from [http://www.openstreetmap.org/ OpenStreetMap]. The data is provided as-is without the code that generated it.

=== Austrian Power Network Grid Model ===

[https://www.apg.at/de/netz/anlagen/leitungsnetz Austrian Power Network Grid] 

=== Danish Power Network Grid Model ===

The data are not directly available, but rather a [https://en.energinet.dk/About-us/Registrations/Formular056 registration form] is required before obtaining access.

It has features not present in the ENTSO-E STUM (see below):

*It's a full non-linear model with all the reactive power demand, P and Q capabilities of gens and shunt reactive power compensation.
*It lists the power capabilities of the generators and their fuel type (wind/solar/gas etc), not just the dispatch.
*They seem to have separated RE feed-in from the load, which wasn't the case for STUM where wind and solar are lumped with the load as residual load.

 What's missing are geocoordinates for the substations (which can be read off roughly from the JPG map) and time-dependence of the loads and/or variable generators. For Denmark, which has many CHP units, it would also be useful to know the heat demand and how the CHP units are operated.

=== ENTSO-E Interactive Grid Map ===

ENTSO-E announced its [https://www.entsoe.eu/map/Pages/default.aspx Interactive ENTSO-E Transmission Network Map] in March 2016.

The map uses [http://www.openstreetmap.org/ OpenStreetMap] as a background and [https://www.mapbox.com/about/maps/ Mapbox] for displaying the map data.

The map is based on the ENTSO-E static grid map, which is based on the TSOs' own maps. It is known to be an approximate artistic representation rather than an accurate geographical map. Some power plants may be incorrectly labelled (e.g. fuel type may not be accurate).

The map includes information on the number of circuits and the voltage levels of transmission lines.

Information, including all geographical coordinates, can be extracted from the web API, but requires further topological processing to be turned into an electrical network model. Lines need to be connected, etc. The [https://github.com/bdw/GridKit GridKit] project provides code for this purpose and has released an [https://zenodo.org/record/55853 unofficial dataset], which forms an electrical network model complete with buses, links, generators and transformers, full geographic coordinates, as well as all electrical metadata contained in the ENTSO-E map.

 

=== ENTSO-E Static Grid Map ===

ENTSO-E releases [https://www.entsoe.eu/publications/order-maps-and-publications/electronic-grid-maps/Pages/default.aspx maps of the European transmission grid], both electronically and in paper form.

The maps for the whole ENTSO-E system are in the projection [http://prj2epsg.org/epsg/3034 EPSG 3034], which is a [https://en.wikipedia.org/wiki/Lambert_conformal_conic_projection Lambert Conformal Conic projection]. The lower left corner is approximately at (lon,lat) = (-9.5,28) and the upper left corner is at (75.5,58.5). This was checked in the [https://github.com/nworbmot/georef-bialek/ georef-bialek github project].

 

 

 

=== ENTSO-E STUM ===

ENTSO-E makes available a model of the European transmission system. Registration is required to download it on the [https://www.entsoe.eu/stum/ ENTSO-E STUM] page. It is not totally clear what one may and may not do with it (e.g. whether it is possible to publish results derived from it or an aggregation of the nodes, etc.).

The first version of the model was released in the CIM XML-based format for the old UCTE area. The model was a winter snapshot for 2020, including TYNDP projects. The node names were obscured so that the model was unusable. Line capacities were missing.

The second version, published in June 2015 as Excel spreadsheets, is more useful. It contains the whole ENTSO-E area with the exception of Norway, Sweden, Cyrus and Iceland. The node names are the same as those used by the TSOs. Quoting from the documentation: "It represents the power system of the ENTSO-E members for 2030 in Vision I of the TYNDP 2014", i.e. it includes planned TYNDP projects. It includes all nodes, lines, transformers and aggregated loads and generators at each node for one snapshot. Line data includes series reactance and resistance, but not line length or capacity or number of circuits or wires per circuit bundle. Geolocation data for the nodes is missing. Node names are recognisable from the substation names on the ENTSO-E map. The model is intended for a linear load flow only. It is not clear which wind/solar/load snapshot the model represents (it is an "exemplary scenario"). Generators are not distinguished by generation source.

The third version, published in February 2016 as Excel spreadsheets has in addition thermal ratings for most transformers and most transmission lines, along with reactive power feed-in, consumption and compensation, so that a full non-linear power flow can be run on the grid.

= Typical electrical parameters for transmission infrastructure =

== Calculating cable impedances ==

See http://www.openelectrical.org/wiki/index.php?title=Cable_Impedance_Calculations and electrical engineering textbooks.

== Generalities on overhead alternating current transmission lines ==

=== Three-phase power ===

In almost all of the world electrical power is transmitted using alternating current with three phases separated by 120 degrees, see [https://en.wikipedia.org/wiki/Three-phase_electric_power Wikipedia: Three-phase electric power].

For this reason the cables on power lines are bundled in groups of three.

(Exceptions include: direct current power lines and some [https://en.wikipedia.org/wiki/Railway_electrification_system transmission systems for supplying trains], which are e.g. in Germany two-phase and at 16.7 Hz.)

Current I and current limits are almost always quoted per phase.

Voltage in the transmission system is almost always quoted as the phase-to-phase potential difference, often called line-to-line voltage V_{LL}, since this is the easiest value to measure. It is related to the line-to-ground or line-to-neutral potential difference V_{LN} by V_{LL} = \sqrt{3} V_{LN}.

The apparent power transported in each phase is give by I*V_{LN}, so that for a complete transmission circuit the power is three times this value:

S = 3*I*V_{LN} = \sqrt(3)*I*V_{LL}

Often it is assumed that the voltage and current magnitudes are the same in each phase, i.e. that the system is balanced and symmetric. This should be the case in the normal operation of the transmission system. The impedances and limits below are quoted assuming that the system is balanced, so that only positive sequence impedances are given. See [https://en.wikipedia.org/wiki/Symmetrical_components Wikipedia: Symmetrical components].

In an unbalanced system, the three phases can be described using the positive-, negative- and zero-sequence components, where the impedances are different for each sequence.

 

=== Bundled conductors ===

See [https://en.wikipedia.org/wiki/Overhead_power_line#Bundle_conductors Wikipedia: Overhead power line: Bundle conductors].

Often the conducting wires for each phase are separated into bundles of several parallel wires, connected at intervals by spacers. This has several advantages: the higher surface area increases the current-carrying capacity, which is limited by the [https://en.wikipedia.org/wiki/Skin_effect skin effect], it reduces inductance and it helps to cool the wires.

=== Circuits ===

Each group of three phases is called a circuit. Power-carrying capability can be increased by having several circuits on a single pylon, so that wire bundles always appear in multiples of 3 in power lines.

 

== European 50 Hz transmission lines ==

The main European alternating current (AC) electricity system is operated at 50 Hz. (Other networks, such as those for electrified trains, operate at other frequencies and some transmission lines use direct current.)

On the continent AC transmission voltages are typically 220 kV or 380 kV (sometimes quoted as 400 kV, since network operators often run their grid above nominal voltage to reduce network losses).

220 kV overhead lines are typically configured with a bundle of 2 wires per phase with wires of cross-section Al/St 240/40.

380 kV overhead lines are typically configured with a bundle of 4 wires per phase with wires of cross-section Al/St 240/40.

We now list the impedances of the transmission lines, which can be used for example in the [http://www.electrical4u.com/medium-transmission-line/ lumped pi model].

In the table the thermal limit for the current is calculated as 645 A per wire at an outside temperature of 20 degrees Celsius.

The thermal limit for the apparent power S is derived from the per-phase current limit I and the line-to-line voltage V by S = \sqrt{3}VI.

== European 50 Hz high voltage transformers ==

Typical 380/220 kV transformers have a nominal power of around 400-500 MVA and a per unit series reactance of around 0.08-0.1.

TODO: references

== Combining electrical parameters for multiple circuits ==

In the table above, the impedances are quoted for a single circuit. The resistance and inductive reactance decrease proportional to the number of parallel circuits (with small modifications to the inductance due to the different geometry of the parallel circuits). Similarly the capacitance increases proportional to the number of parallel circuits (again, roughly because of changing geometry).

=== SciGRID ===

[http://scigrid.de/ SciGRID] is a project which started in 2014 and will be running for three years. The aim of SciGRID is to develop an open and free model of the European transmission network based on data from the [http://www.openstreetmap.org/ OpenStreetMap]. It is carried out by [http://www.next-energy.de/ NEXT ENERGY - EWE Research Centre for Energy Technology], an independent non-profit institute at the University of Oldenburg, Germany, and funded by the [https://www.bmbf.de/ German Ministry of Education and Research],  and the initiative [http://forschung-stromnetze.info/ Zukunftsfähige Stromnetze].

An unofficial, post-processed version of SciGRID version 0.2 for Germany with attached load, generation and transformers is available as a [https://github.com/FRESNA/PyPSA/tree/master/examples/scigrid-de PyPSA example], see also [http://pypsa.org/index.html#screenshots-and-example-jupyter-ipython-notebooks screenshots]. 

=== GridKit European Dataset ===

[https://github.com/bdw/GridKit GridKit] uses spatial and topological analysis to transform map objects from [http://www.openstreetmap.org/ OpenStreetMap] into a network model of the electric power system. It has been developed in the context of the [http://scigrid.de/ SciGRID] project at the [http://www.next-energy.de/ NEXT ENERGY - EWE Research Centre for Energy Technology], to investigate the possibility of 'heuristic' analysis to augment the route-based analysis used in [http://scigrid.de/ SciGRID]. This has been implemented as a series of scripts for the PostgreSQL database using the PostGIS spatial extensions.

[https://zenodo.org/record/47317 Data extracts] are provided for Europe and North America in a similar CSV format to [http://scigrid.de/ SciGRID].

 

=== osmTGmod Model ===

[https://github.com/maltesc/osmTGmod osmTGmod] is a load-flow model of the German transmission-gird, based on the free geo-database [http://www.openstreetmap.org/ OpenStreetMap] (OSM). The model, respectively the heuristic abstraction process employs a PostgreSQL-database extended by PostGIS. The key part of the abstraction process is implemented in SQL and ProstgreSQL's procedural language pl/pgSQL. The abstraction and all additional modules are controlled by a Python-environment.

 

=== Bialek European Model ===

The 2nd version of the [http://www.powerworld.com/knowledge-base/updated-and-validated-power-flow-model-of-the-main-continental-european-transmission-network Bialek European Model] is downloadable as an Excel file and in the format of the proprietary modelling software [http://www.powerworld.com/ PowerWorld]. The model covers voltages from 110 kV (a single line in the Balkans) up to 380 kV. It is released under a Public Domain Dedication. 

The 1st version was released in 2002-2004 and is no longer available (see [http://web.archive.org/web/20100525115039/http://www.see.ed.ac.uk/~jbialek/Europe_load_flow/ Archive mirror]). The 1st version did not contain the Balkans region.

The methodology and validation for the 1st version of the model can be found in the paper [http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=1425573 Approximate model of European interconnected system as a benchmark system to study effects of cross-border trades] by Zhou and Bialek, 2005.

The model contains the impedances and number of circuits of each line, but not the length (which can in principle be determined from the impedance and number of circuits, given standard line parameters). Only cross-border lines are assigned thermal capacities.

There is currently no coordinate dataset for the buses. The PowerWorld file contains spatial data, but in an unknown projection. The [https://github.com/nworbmot/georef-bialek/ georef-bialek github project] is an attempt to fix this; there is also a [https://zenodo.org/record/35177 geo-referenced version] from Tue Vissing Jensen.

=== DIW ELMOD-DE open model of Germany ===

[http://www.diw.de/de/diw_01.c.528493.de/forschung_beratung/nachhaltigkeit/umwelt/verkehr/energie/modelle/elmod.html#ELMOD-DE ELMOD-DE] is an open model of the German electricity system developed at DIW and TU Berlin, which includes both a model of the high voltage transmission network, power plants, hourly load and weather data for the year 2012 and GAMS code to run linear optimisation simulations. It contains 438 geo-referenced network nodes and 697 transmission lines at 380 kV and 220 kV. Transformers are not modelled but per unit line series impedances are adjusted to the voltage level.

The model includes 47 pages of documentation.

The transmission data was, according to the documentation, derived from the VDE and TSO maps and from [http://www.openstreetmap.org/ OpenStreetMap]. The data is provided as-is without the code that generated it.

 

=== National Grid Model ===

[http://www2.nationalgrid.com/UK/Industry-information/Future-of-Energy/Electricity-Ten-Year-Statement/ National Grid Electricity Ten Year Statement 2014 Model]

[http://www2.nationalgrid.com/uk/services/land-and-development/planning-authority/shape-files/ Shapefiles] and [http://www2.nationalgrid.com/uk/services/land-and-development/planning-authority/electricity-network-overhead-lines/ maps] of tower, lines, cables and substations. 

=== Austrian Power Network Grid Model ===

[https://www.apg.at/de/netz/anlagen/leitungsnetz Austrian Power Network Grid] 

=== Danish Power Network Grid Model ===

The data are not directly available, but rather a [https://en.energinet.dk/About-us/Registrations/Formular056 registration form] is required before obtaining access.

It has features not present in the ENTSO-E STUM (see below):

*It's a full non-linear model with all the reactive power demand, P and Q capabilities of gens and shunt reactive power compensation.
*It lists the power capabilities of the generators and their fuel type (wind/solar/gas etc), not just the dispatch.
*They seem to have separated RE feed-in from the load, which wasn't the case for STUM where wind and solar are lumped with the load as residual load.

 What's missing are geocoordinates for the substations (which can be read off roughly from the JPG map) and time-dependence of the loads and/or variable generators. For Denmark, which has many CHP units, it would also be useful to know the heat demand and how the CHP units are operated.

=== ENTSO-E Interactive Grid Map ===

ENTSO-E announced its [https://www.entsoe.eu/map/Pages/default.aspx Interactive ENTSO-E Transmission Network Map] in March 2016.

The map uses [http://www.openstreetmap.org/ OpenStreetMap] as a background and [https://www.mapbox.com/about/maps/ Mapbox] for displaying the map data.

The map is based on the ENTSO-E static grid map, which is based on the TSOs' own maps. It is known to be an approximate artistic representation rather than an accurate geographical map. Some power plants may be incorrectly labelled (e.g. fuel type may not be accurate).

The map includes information on the number of circuits and the voltage levels of transmission lines.

Information, including all geographical coordinates, can be extracted from the web API, but requires further topological processing to be turned into an electrical network model. Lines need to be connected, etc. The [https://github.com/bdw/GridKit GridKit] project provides code for this purpose and has released an [https://zenodo.org/record/55853 unofficial dataset], which forms an electrical network model complete with buses, links, generators and transformers, full geographic coordinates, as well as all electrical metadata contained in the ENTSO-E map.

 

=== ENTSO-E Static Grid Map ===

ENTSO-E releases [https://www.entsoe.eu/publications/order-maps-and-publications/electronic-grid-maps/Pages/default.aspx maps of the European transmission grid], both electronically and in paper form.

The maps for the whole ENTSO-E system are in the projection [http://prj2epsg.org/epsg/3034 EPSG 3034], which is a [https://en.wikipedia.org/wiki/Lambert_conformal_conic_projection Lambert Conformal Conic projection]. The lower left corner is approximately at (lon,lat) = (-9.5,28) and the upper left corner is at (75.5,58.5). This was checked in the [https://github.com/nworbmot/georef-bialek/ georef-bialek github project].

 

 

 

=== ENTSO-E STUM ===

ENTSO-E makes available a model of the European transmission system. Registration is required to download it on the [https://www.entsoe.eu/stum/ ENTSO-E STUM] page. It is not totally clear what one may and may not do with it (e.g. whether it is possible to publish results derived from it or an aggregation of the nodes, etc.).

The first version of the model was released in the CIM XML-based format for the old UCTE area. The model was a winter snapshot for 2020, including TYNDP projects. The node names were obscured so that the model was unusable. Line capacities were missing.

The second version, published in June 2015 as Excel spreadsheets, is more useful. It contains the whole ENTSO-E area with the exception of Norway, Sweden, Cyrus and Iceland. The node names are the same as those used by the TSOs. Quoting from the documentation: "It represents the power system of the ENTSO-E members for 2030 in Vision I of the TYNDP 2014", i.e. it includes planned TYNDP projects. It includes all nodes, lines, transformers and aggregated loads and generators at each node for one snapshot. Line data includes series reactance and resistance, but not line length or capacity or number of circuits or wires per circuit bundle. Geolocation data for the nodes is missing. Node names are recognisable from the substation names on the ENTSO-E map. The model is intended for a linear load flow only. It is not clear which wind/solar/load snapshot the model represents (it is an "exemplary scenario"). Generators are not distinguished by generation source.

The third version, published in February 2016 as Excel spreadsheets has in addition thermal ratings for most transformers and most transmission lines, along with reactive power feed-in, consumption and compensation, so that a full non-linear power flow can be run on the grid.

= Typical electrical parameters for transmission infrastructure =

== Calculating cable impedances ==

See http://www.openelectrical.org/wiki/index.php?title=Cable_Impedance_Calculations and electrical engineering textbooks.

== Generalities on overhead alternating current transmission lines ==

=== Three-phase power ===

In almost all of the world electrical power is transmitted using alternating current with three phases separated by 120 degrees, see [https://en.wikipedia.org/wiki/Three-phase_electric_power Wikipedia: Three-phase electric power].

For this reason the cables on power lines are bundled in groups of three.

(Exceptions include: direct current power lines and some [https://en.wikipedia.org/wiki/Railway_electrification_system transmission systems for supplying trains], which are e.g. in Germany two-phase and at 16.7 Hz.)

Current I and current limits are almost always quoted per phase.

Voltage in the transmission system is almost always quoted as the phase-to-phase potential difference, often called line-to-line voltage V_{LL}, since this is the easiest value to measure. It is related to the line-to-ground or line-to-neutral potential difference V_{LN} by V_{LL} = \sqrt{3} V_{LN}.

The apparent power transported in each phase is give by I*V_{LN}, so that for a complete transmission circuit the power is three times this value:

S = 3*I*V_{LN} = \sqrt(3)*I*V_{LL}

Often it is assumed that the voltage and current magnitudes are the same in each phase, i.e. that the system is balanced and symmetric. This should be the case in the normal operation of the transmission system. The impedances and limits below are quoted assuming that the system is balanced, so that only positive sequence impedances are given. See [https://en.wikipedia.org/wiki/Symmetrical_components Wikipedia: Symmetrical components].

In an unbalanced system, the three phases can be described using the positive-, negative- and zero-sequence components, where the impedances are different for each sequence.

 

=== Bundled conductors ===

See [https://en.wikipedia.org/wiki/Overhead_power_line#Bundle_conductors Wikipedia: Overhead power line: Bundle conductors].

Often the conducting wires for each phase are separated into bundles of several parallel wires, connected at intervals by spacers. This has several advantages: the higher surface area increases the current-carrying capacity, which is limited by the [https://en.wikipedia.org/wiki/Skin_effect skin effect], it reduces inductance and it helps to cool the wires.

=== Circuits ===

Each group of three phases is called a circuit. Power-carrying capability can be increased by having several circuits on a single pylon, so that wire bundles always appear in multiples of 3 in power lines.

 

== European 50 Hz transmission lines ==

The main European alternating current (AC) electricity system is operated at 50 Hz. (Other networks, such as those for electrified trains, operate at other frequencies and some transmission lines use direct current.)

On the continent AC transmission voltages are typically 220 kV or 380 kV (sometimes quoted as 400 kV, since network operators often run their grid above nominal voltage to reduce network losses).

220 kV overhead lines are typically configured with a bundle of 2 wires per phase with wires of cross-section Al/St 240/40.

380 kV overhead lines are typically configured with a bundle of 4 wires per phase with wires of cross-section Al/St 240/40.

We now list the impedances of the transmission lines, which can be used for example in the [http://www.electrical4u.com/medium-transmission-line/ lumped pi model].

In the table the thermal limit for the current is calculated as 645 A per wire at an outside temperature of 20 degrees Celsius.

The thermal limit for the apparent power S is derived from the per-phase current limit I and the line-to-line voltage V by S = \sqrt{3}VI.

== European 50 Hz high voltage transformers ==

Typical 380/220 kV transformers have a nominal power of around 400-500 MVA and a per unit series reactance of around 0.08-0.1.

TODO: references

== Combining electrical parameters for multiple circuits ==

In the table above, the impedances are quoted for a single circuit. The resistance and inductive reactance decrease proportional to the number of parallel circuits (with small modifications to the inductance due to the different geometry of the parallel circuits). Similarly the capacitance increases proportional to the number of parallel circuits (again, roughly because of changing geometry).

=== SciGRID ===

[http://scigrid.de/ SciGRID] is a project which started in 2014 and will be running for three years. The aim of SciGRID is to develop an open and free model of the European transmission network based on data from the [http://www.openstreetmap.org/ OpenStreetMap]. It is carried out by [http://www.next-energy.de/ NEXT ENERGY - EWE Research Centre for Energy Technology], an independent non-profit institute at the University of Oldenburg, Germany, and funded by the [https://www.bmbf.de/ German Ministry of Education and Research],  and the initiative [http://forschung-stromnetze.info/ Zukunftsfähige Stromnetze].

An unofficial, post-processed version of SciGRID version 0.2 for Germany with attached load, generation and transformers is available as a [https://github.com/FRESNA/PyPSA/tree/master/examples/scigrid-de PyPSA example], see also [http://pypsa.org/index.html#screenshots-and-example-jupyter-ipython-notebooks screenshots].

It has been developed in the context of the [http://scigrid.de/ SciGRID] project at the [http://www.next-energy.de/ NEXT ENERGY - EWE Research Centre for Energy Technology], to investigate the possibility of 'heuristic' analysis to augment the route-based analysis used in [http://scigrid.de/ SciGRID]. This has been implemented as a series of scripts for the PostgreSQL database using the PostGIS spatial extensions.

[https://zenodo.org/record/47317 Data extracts] are provided for Europe and North America in a similar CSV format to [http://scigrid.de/ SciGRID].

 

=== osmTGmod Model ===

[https://github.com/maltesc/osmTGmod osmTGmod] is a load-flow model of the German transmission-gird, based on the free geo-database [http://www.openstreetmap.org/ OpenStreetMap] (OSM). The model, respectively the heuristic abstraction process employs a PostgreSQL-database extended by PostGIS. The key part of the abstraction process is implemented in SQL and ProstgreSQL's procedural language pl/pgSQL. The abstraction and all additional modules are controlled by a Python-environment.

 

=== Bialek European Model ===

The 2nd version of the [http://www.powerworld.com/knowledge-base/updated-and-validated-power-flow-model-of-the-main-continental-european-transmission-network Bialek European Model] is downloadable as an Excel file and in the format of the proprietary modelling software [http://www.powerworld.com/ PowerWorld]. The model covers voltages from 110 kV (a single line in the Balkans) up to 380 kV. It is released under a Public Domain Dedication. 

The 1st version was released in 2002-2004 and is no longer available (see [http://web.archive.org/web/20100525115039/http://www.see.ed.ac.uk/~jbialek/Europe_load_flow/ Archive mirror]). The 1st version did not contain the Balkans region.

The methodology and validation for the 1st version of the model can be found in the paper [http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=1425573 Approximate model of European interconnected system as a benchmark system to study effects of cross-border trades] by Zhou and Bialek, 2005.

The model contains the impedances and number of circuits of each line, but not the length (which can in principle be determined from the impedance and number of circuits, given standard line parameters). Only cross-border lines are assigned thermal capacities.

There is currently no coordinate dataset for the buses. The PowerWorld file contains spatial data, but in an unknown projection. The [https://github.com/nworbmot/georef-bialek/ georef-bialek github project] is an attempt to fix this; there is also a [https://zenodo.org/record/35177 geo-referenced version] from Tue Vissing Jensen.

=== DIW ELMOD-DE open model of Germany ===

[http://www.diw.de/de/diw_01.c.528493.de/forschung_beratung/nachhaltigkeit/umwelt/verkehr/energie/modelle/elmod.html#ELMOD-DE ELMOD-DE] is an open model of the German electricity system developed at DIW and TU Berlin, which includes both a model of the high voltage transmission network, power plants, hourly load and weather data for the year 2012 and GAMS code to run linear optimisation simulations. It contains 438 geo-referenced network nodes and 697 transmission lines at 380 kV and 220 kV. Transformers are not modelled but per unit line series impedances are adjusted to the voltage level.

The model includes 47 pages of documentation.

The transmission data was, according to the documentation, derived from the VDE and TSO maps and from [http://www.openstreetmap.org/ OpenStreetMap]. The data is provided as-is without the code that generated it.

 

=== National Grid Model ===

=== Austrian Power Network Grid Model ===

[https://www.apg.at/de/netz/anlagen/leitungsnetz Austrian Power Network Grid] 

=== Danish Power Network Grid Model ===

The data are not directly available, but rather a [https://en.energinet.dk/About-us/Registrations/Formular056 registration form] is required before obtaining access.

It has features not present in the ENTSO-E STUM (see below):

*It's a full non-linear model with all the reactive power demand, P and Q capabilities of gens and shunt reactive power compensation.
*It lists the power capabilities of the generators and their fuel type (wind/solar/gas etc), not just the dispatch.
*They seem to have separated RE feed-in from the load, which wasn't the case for STUM where wind and solar are lumped with the load as residual load.

 What's missing are geocoordinates for the substations (which can be read off roughly from the JPG map) and time-dependence of the loads and/or variable generators. For Denmark, which has many CHP units, it would also be useful to know the heat demand and how the CHP units are operated.

=== ENTSO-E Interactive Grid Map ===

ENTSO-E announced its [https://www.entsoe.eu/map/Pages/default.aspx Interactive ENTSO-E Transmission Network Map] in March 2016.

The map uses [http://www.openstreetmap.org/ OpenStreetMap] as a background and [https://www.mapbox.com/about/maps/ Mapbox] for displaying the map data.

The map is based on the ENTSO-E static grid map, which is based on the TSOs' own maps. It is known to be an approximate artistic representation rather than an accurate geographical map. Some power plants may be incorrectly labelled (e.g. fuel type may not be accurate).

The map includes information on the number of circuits and the voltage levels of transmission lines.

Information, including all geographical coordinates, can be extracted from the web API, but requires further topological processing to be turned into an electrical network model. Lines need to be connected, etc. The [https://github.com/bdw/GridKit GridKit] project provides code for this purpose and has released an [https://zenodo.org/record/55853 unofficial dataset], which forms an electrical network model complete with buses, links, generators and transformers, full geographic coordinates, as well as all electrical metadata contained in the ENTSO-E map.

 

=== ENTSO-E Static Grid Map ===

ENTSO-E releases [https://www.entsoe.eu/publications/order-maps-and-publications/electronic-grid-maps/Pages/default.aspx maps of the European transmission grid], both electronically and in paper form.

The maps for the whole ENTSO-E system are in the projection [http://prj2epsg.org/epsg/3034 EPSG 3034], which is a [https://en.wikipedia.org/wiki/Lambert_conformal_conic_projection Lambert Conformal Conic projection]. The lower left corner is approximately at (lon,lat) = (-9.5,28) and the upper left corner is at (75.5,58.5). This was checked in the [https://github.com/nworbmot/georef-bialek/ georef-bialek github project].

 

 

 

=== ENTSO-E STUM ===

ENTSO-E makes available a model of the European transmission system. Registration is required to download it on the [https://www.entsoe.eu/stum/ ENTSO-E STUM] page. It is not totally clear what one may and may not do with it (e.g. whether it is possible to publish results derived from it or an aggregation of the nodes, etc.).

The first version of the model was released in the CIM XML-based format for the old UCTE area. The model was a winter snapshot for 2020, including TYNDP projects. The node names were obscured so that the model was unusable. Line capacities were missing.

The second version, published in June 2015 as Excel spreadsheets, is more useful. It contains the whole ENTSO-E area with the exception of Norway, Sweden, Cyrus and Iceland. The node names are the same as those used by the TSOs. Quoting from the documentation: "It represents the power system of the ENTSO-E members for 2030 in Vision I of the TYNDP 2014", i.e. it includes planned TYNDP projects. It includes all nodes, lines, transformers and aggregated loads and generators at each node for one snapshot. Line data includes series reactance and resistance, but not line length or capacity or number of circuits or wires per circuit bundle. Geolocation data for the nodes is missing. Node names are recognisable from the substation names on the ENTSO-E map. The model is intended for a linear load flow only. It is not clear which wind/solar/load snapshot the model represents (it is an "exemplary scenario"). Generators are not distinguished by generation source.

The third version, published in February 2016 as Excel spreadsheets has in addition thermal ratings for most transformers and most transmission lines, along with reactive power feed-in, consumption and compensation, so that a full non-linear power flow can be run on the grid.

= Typical electrical parameters for transmission infrastructure =

== Calculating cable impedances ==

See http://www.openelectrical.org/wiki/index.php?title=Cable_Impedance_Calculations and electrical engineering textbooks.

== Generalities on overhead alternating current transmission lines ==

=== Three-phase power ===

In almost all of the world electrical power is transmitted using alternating current with three phases separated by 120 degrees, see [https://en.wikipedia.org/wiki/Three-phase_electric_power Wikipedia: Three-phase electric power].

For this reason the cables on power lines are bundled in groups of three.

(Exceptions include: direct current power lines and some [https://en.wikipedia.org/wiki/Railway_electrification_system transmission systems for supplying trains], which are e.g. in Germany two-phase and at 16.7 Hz.)

Current I and current limits are almost always quoted per phase.

Voltage in the transmission system is almost always quoted as the phase-to-phase potential difference, often called line-to-line voltage V_{LL}, since this is the easiest value to measure. It is related to the line-to-ground or line-to-neutral potential difference V_{LN} by V_{LL} = \sqrt{3} V_{LN}.

The apparent power transported in each phase is give by I*V_{LN}, so that for a complete transmission circuit the power is three times this value:

S = 3*I*V_{LN} = \sqrt(3)*I*V_{LL}

Often it is assumed that the voltage and current magnitudes are the same in each phase, i.e. that the system is balanced and symmetric. This should be the case in the normal operation of the transmission system. The impedances and limits below are quoted assuming that the system is balanced, so that only positive sequence impedances are given. See [https://en.wikipedia.org/wiki/Symmetrical_components Wikipedia: Symmetrical components].

In an unbalanced system, the three phases can be described using the positive-, negative- and zero-sequence components, where the impedances are different for each sequence.

 

=== Bundled conductors ===

See [https://en.wikipedia.org/wiki/Overhead_power_line#Bundle_conductors Wikipedia: Overhead power line: Bundle conductors].

Often the conducting wires for each phase are separated into bundles of several parallel wires, connected at intervals by spacers. This has several advantages: the higher surface area increases the current-carrying capacity, which is limited by the [https://en.wikipedia.org/wiki/Skin_effect skin effect], it reduces inductance and it helps to cool the wires.

=== Circuits ===

Each group of three phases is called a circuit. Power-carrying capability can be increased by having several circuits on a single pylon, so that wire bundles always appear in multiples of 3 in power lines.

 

== European 50 Hz transmission lines ==

The main European alternating current (AC) electricity system is operated at 50 Hz. (Other networks, such as those for electrified trains, operate at other frequencies and some transmission lines use direct current.)

On the continent AC transmission voltages are typically 220 kV or 380 kV (sometimes quoted as 400 kV, since network operators often run their grid above nominal voltage to reduce network losses).

220 kV overhead lines are typically configured with a bundle of 2 wires per phase with wires of cross-section Al/St 240/40.

380 kV overhead lines are typically configured with a bundle of 4 wires per phase with wires of cross-section Al/St 240/40.

We now list the impedances of the transmission lines, which can be used for example in the [http://www.electrical4u.com/medium-transmission-line/ lumped pi model].

In the table the thermal limit for the current is calculated as 645 A per wire at an outside temperature of 20 degrees Celsius.

The thermal limit for the apparent power S is derived from the per-phase current limit I and the line-to-line voltage V by S = \sqrt{3}VI.

== European 50 Hz high voltage transformers ==

Typical 380/220 kV transformers have a nominal power of around 400-500 MVA and a per unit series reactance of around 0.08-0.1.

TODO: references

== Combining electrical parameters for multiple circuits ==

In the table above, the impedances are quoted for a single circuit. The resistance and inductive reactance decrease proportional to the number of parallel circuits (with small modifications to the inductance due to the different geometry of the parallel circuits). Similarly the capacitance increases proportional to the number of parallel circuits (again, roughly because of changing geometry).

=== SciGRID ===

[http://scigrid.de/ SciGRID] is a project which started in 2014 and will be running for three years. The aim of SciGRID is to develop an open and free model of the European transmission network based on data from the [http://www.openstreetmap.org/ OpenStreetMap]. It is carried out by [http://www.next-energy.de/ NEXT ENERGY - EWE Research Centre for Energy Technology], an independent non-profit institute at the University of Oldenburg, Germany, and funded by the [https://www.bmbf.de/ German Ministry of Education and Research],  and the initiative [http://forschung-stromnetze.info/ Zukunftsfähige Stromnetze].

An unofficial, post-processed version of SciGRID version 0.2 for Germany with attached load, generation and transformers is available as a [https://github.com/FRESNA/PyPSA/tree/master/examples/scigrid-de PyPSA example], see also [http://pypsa.org/index.html#screenshots-and-example-jupyter-ipython-notebooks screenshots]. 

=== GridKit European Dataset ===

[https://github.com/bdw/GridKit GridKit] uses spatial and topological analysis to transform map objects from [http://www.openstreetmap.org/ OpenStreetMap] into a network model of the electric power system. It has been developed in the context of the [http://scigrid.de/ SciGRID] project at the [http://www.next-energy.de/ NEXT ENERGY - EWE Research Centre for Energy Technology], to investigate the possibility of 'heuristic' analysis to augment the route-based analysis used in [http://scigrid.de/ SciGRID]. This has been implemented as a series of scripts for the PostgreSQL database using the PostGIS spatial extensions.

[https://zenodo.org/record/47317 Data extracts] are provided for Europe and North America in a similar CSV format to [http://scigrid.de/ SciGRID].

 

=== osmTGmod Model ===

[https://github.com/maltesc/osmTGmod osmTGmod] is a load-flow model of the German transmission-gird, based on the free geo-database [http://www.openstreetmap.org/ OpenStreetMap] (OSM). The model, respectively the heuristic abstraction process employs a PostgreSQL-database extended by PostGIS. The key part of the abstraction process is implemented in SQL and ProstgreSQL's procedural language pl/pgSQL. The abstraction and all additional modules are controlled by a Python-environment.

 

=== Bialek European Model ===

The 2nd version of the [http://www.powerworld.com/knowledge-base/updated-and-validated-power-flow-model-of-the-main-continental-european-transmission-network Bialek European Model] is downloadable as an Excel file and in the format of the proprietary modelling software [http://www.powerworld.com/ PowerWorld]. The model covers voltages from 110 kV (a single line in the Balkans) up to 380 kV. It is released under a Public Domain Dedication. 

The 1st version was released in 2002-2004 and is no longer available (see [http://web.archive.org/web/20100525115039/http://www.see.ed.ac.uk/~jbialek/Europe_load_flow/ Archive mirror]). The 1st version did not contain the Balkans region.

The methodology and validation for the 1st version of the model can be found in the paper [http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=1425573 Approximate model of European interconnected system as a benchmark system to study effects of cross-border trades] by Zhou and Bialek, 2005.

The model contains the impedances and number of circuits of each line, but not the length (which can in principle be determined from the impedance and number of circuits, given standard line parameters). Only cross-border lines are assigned thermal capacities.

There is currently no coordinate dataset for the buses. The PowerWorld file contains spatial data, but in an unknown projection.

[http://www.diw.de/de/diw_01.c.528493.de/forschung_beratung/nachhaltigkeit/umwelt/verkehr/energie/modelle/elmod.html#ELMOD-DE ELMOD-DE] is an open model of the German electricity system developed at DIW and TU Berlin, which includes both a model of the high voltage transmission network, power plants, hourly load and weather data for the year 2012 and GAMS code to run linear optimisation simulations. It contains 438 geo-referenced network nodes and 697 transmission lines at 380 kV and 220 kV. Transformers are not modelled but per unit line series impedances are adjusted to the voltage level.

The model includes 47 pages of documentation.

The transmission data was, according to the documentation, derived from the VDE and TSO maps and from [http://www.openstreetmap.org/ OpenStreetMap]. The data is provided as-is without the code that generated it.

=== Danish Power Network Grid Model ===

[http://www.energinet.dk/DA/El/Udvikling-af-elsystemet/Netplanlaegning/Sider/Formular-Til-Download-Af-Netdata.aspx Danish Power Network Grid] 

It has features not present in the ENTSO-E STUM (see below):

*It's a full non-linear model with all the reactive power demand, P and Q capabilities of gens and shunt reactive power compensation.
*It lists the power capabilities of the generators and their fuel type (wind/solar/gas etc), not just the dispatch.
*They seem to have separated RE feed-in from the load, which wasn't the case for STUM where wind and solar are lumped with the load as residual load.

 What's missing are geocoordinates for the substations (which can be read off roughly from the JPG map) and time-dependence of the loads and/or variable generators. For Denmark, which has many CHP units, it would also be useful to know the heat demand and how the CHP units are operated.

=== ENTSO-E Interactive Grid Map ===

ENTSO-E announced its [https://www.entsoe.eu/map/Pages/default.aspx Interactive ENTSO-E Transmission Network Map] in March 2016.

The map uses [http://www.openstreetmap.org/ OpenStreetMap] as a background and [https://www.mapbox.com/about/maps/ Mapbox] for displaying the map data.

The map is based on the ENTSO-E static grid map, which is based on the TSOs' own maps. It is known to be an approximate artistic representation rather than an accurate geographical map. Some power plants may be incorrectly labelled (e.g. fuel type may not be accurate).

The map includes information on the number of circuits and the voltage levels of transmission lines.

Information, including all geographical coordinates, can be extracted from the web API, but requires further topological processing to be turned into an electrical network model. Lines need to be connected, etc. The [https://github.com/bdw/GridKit GridKit] project provides code for this purpose and has released an [https://zenodo.org/record/55853 unofficial dataset], which forms an electrical network model complete with buses, links, generators and transformers, full geographic coordinates, as well as all electrical metadata contained in the ENTSO-E map.

 

=== ENTSO-E Static Grid Map ===

ENTSO-E releases [https://www.entsoe.eu/publications/order-maps-and-publications/electronic-grid-maps/Pages/default.aspx maps of the European transmission grid], both electronically and in paper form.

The maps for the whole ENTSO-E system are in the projection [http://prj2epsg.org/epsg/3034 EPSG 3034], which is a [https://en.wikipedia.org/wiki/Lambert_conformal_conic_projection Lambert Conformal Conic projection]. The lower left corner is approximately at (lon,lat) = (-9.5,28) and the upper left corner is at (75.5,58.5). This was checked in the [https://github.com/nworbmot/georef-bialek/ georef-bialek github project].

 

 

 

=== ENTSO-E STUM ===

ENTSO-E makes available a model of the European transmission system. Registration is required to download it on the [https://www.entsoe.eu/stum/ ENTSO-E STUM] page. It is not totally clear what one may and may not do with it (e.g. whether it is possible to publish results derived from it or an aggregation of the nodes, etc.).

The first version of the model was released in the CIM XML-based format for the old UCTE area. The model was a winter snapshot for 2020, including TYNDP projects. The node names were obscured so that the model was unusable. Line capacities were missing.

The second version, published in June 2015 as Excel spreadsheets, is more useful. It contains the whole ENTSO-E area with the exception of Norway, Sweden, Cyrus and Iceland. The node names are the same as those used by the TSOs. Quoting from the documentation: "It represents the power system of the ENTSO-E members for 2030 in Vision I of the TYNDP 2014", i.e. it includes planned TYNDP projects. It includes all nodes, lines, transformers and aggregated loads and generators at each node for one snapshot. Line data includes series reactance and resistance, but not line length or capacity or number of circuits or wires per circuit bundle. Geolocation data for the nodes is missing. Node names are recognisable from the substation names on the ENTSO-E map. The model is intended for a linear load flow only. It is not clear which wind/solar/load snapshot the model represents (it is an "exemplary scenario"). Generators are not distinguished by generation source.

The third version, published in February 2016 as Excel spreadsheets has in addition thermal ratings for most transformers and most transmission lines, along with reactive power feed-in, consumption and compensation, so that a full non-linear power flow can be run on the grid.

= Typical electrical parameters for transmission infrastructure =

== Calculating cable impedances ==

See http://www.openelectrical.org/wiki/index.php?title=Cable_Impedance_Calculations and electrical engineering textbooks.

== Generalities on overhead alternating current transmission lines ==

=== Three-phase power ===

In almost all of the world electrical power is transmitted using alternating current with three phases separated by 120 degrees, see [https://en.wikipedia.org/wiki/Three-phase_electric_power Wikipedia: Three-phase electric power].

For this reason the cables on power lines are bundled in groups of three.

(Exceptions include: direct current power lines and some [https://en.wikipedia.org/wiki/Railway_electrification_system transmission systems for supplying trains], which are e.g. in Germany two-phase and at 16.7 Hz.)

Current I and current limits are almost always quoted per phase.

Voltage in the transmission system is almost always quoted as the phase-to-phase potential difference, often called line-to-line voltage V_{LL}, since this is the easiest value to measure. It is related to the line-to-ground or line-to-neutral potential difference V_{LN} by V_{LL} = \sqrt{3} V_{LN}.

The apparent power transported in each phase is give by I*V_{LN}, so that for a complete transmission circuit the power is three times this value:

S = 3*I*V_{LN} = \sqrt(3)*I*V_{LL}

Often it is assumed that the voltage and current magnitudes are the same in each phase, i.e. that the system is balanced and symmetric. This should be the case in the normal operation of the transmission system. The impedances and limits below are quoted assuming that the system is balanced, so that only positive sequence impedances are given. See [https://en.wikipedia.org/wiki/Symmetrical_components Wikipedia: Symmetrical components].

In an unbalanced system, the three phases can be described using the positive-, negative- and zero-sequence components, where the impedances are different for each sequence.

 

=== Bundled conductors ===

See [https://en.wikipedia.org/wiki/Overhead_power_line#Bundle_conductors Wikipedia: Overhead power line: Bundle conductors].

Often the conducting wires for each phase are separated into bundles of several parallel wires, connected at intervals by spacers. This has several advantages: the higher surface area increases the current-carrying capacity, which is limited by the [https://en.wikipedia.org/wiki/Skin_effect skin effect], it reduces inductance and it helps to cool the wires.

=== Circuits ===

Each group of three phases is called a circuit. Power-carrying capability can be increased by having several circuits on a single pylon, so that wire bundles always appear in multiples of 3 in power lines.

 

== European 50 Hz transmission lines ==

The main European alternating current (AC) electricity system is operated at 50 Hz. (Other networks, such as those for electrified trains, operate at other frequencies and some transmission lines use direct current.)

On the continent AC transmission voltages are typically 220 kV or 380 kV (sometimes quoted as 400 kV, since network operators often run their grid above nominal voltage to reduce network losses).

220 kV overhead lines are typically configured with a bundle of 2 wires per phase with wires of cross-section Al/St 240/40.

380 kV overhead lines are typically configured with a bundle of 4 wires per phase with wires of cross-section Al/St 240/40.

We now list the impedances of the transmission lines, which can be used for example in the [http://www.electrical4u.com/medium-transmission-line/ lumped pi model].

In the table the thermal limit for the current is calculated as 645 A per wire at an outside temperature of 20 degrees Celsius.

The thermal limit for the apparent power S is derived from the per-phase current limit I and the line-to-line voltage V by S = \sqrt{3}VI.

== European 50 Hz high voltage transformers ==

Typical 380/220 kV transformers have a nominal power of around 400-500 MVA and a per unit series reactance of around 0.08-0.1.

TODO: references

== Combining electrical parameters for multiple circuits ==

In the table above, the impedances are quoted for a single circuit. The resistance and inductive reactance decrease proportional to the number of parallel circuits (with small modifications to the inductance due to the different geometry of the parallel circuits). Similarly the capacitance increases proportional to the number of parallel circuits (again, roughly because of changing geometry).

Open Energy Modelling Workshop - Milano 2016

2016-09-28T20:14:09Z

Konstantinos Syranidis: /* Participants */

This is the wiki page for the upcoming '''Fifth Workshop of the [http://openmod-initiative.org/ Open Energy Modelling Initiative]''', a grass-roots organization of modellers from various European research institutes and universities. After two workshops in Berlin, one in London and one in Stockholm, the next one will be in '''Milano, Italy hosted by the [http://www.energia.polimi.it/english/index.php? Politecnico di Milano – Department of Energy (Mi Bovisa branch)]'''.The workshop takes place on '''27-28 October, 2016'''. As always, there is no registration fee, so feel free to join! 

This wiki page will be updated frequently with a program and practical information. All participants are invited to contribute suggestions of different sessions to be included in the program. And in the meantime, feel free to register on the [https://groups.google.com/forum/#!forum/openmod-initiative mailing list] where all things regarding energy modelling are discussed. 

== Background ==

Energy models are widely used for policy advice and research. They serve to answer questions on energy policy, decarbonization, and transitions towards renewable energy sources. Yet, most energy models are black boxes – even to fellow researchers. This is what we want to change. We are a group of modellers from various universities and research institutes who want to promote open energy modelling. We believe that Open Source models and Open Data will advance knowledge and lead to better energy policies. Our mission is to enable Open Source energy modelling by providing a platform for collaboration as well as tools along the full value chain of energy economics and energy system models. That is why we founded the Open Energy Modelling Initiative (openmod initiative) just a year ago. You are welcome to join us for our next workshop! 

 

The bulk of the workshop consists of breakout groups, where specific topics are discussed and worked upon. People can suggest breakout topics in advance, but to keep the workshop fluid and adaptable, topics can also be suggested on the day.

== Practical information ==
