SciGrid

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. It is carried out by NEXT ENERGY - EWE Research Centre for Energy Technology, an independent non-profit institute at the University of Oldenburg, Germany, and funded by the German Ministry of Education and Research, and the initiative Zukunftsfähige Stromnetze.

Bialek European Model

The 2nd version of the Bialek European Model is downloadable as an Excel file and in the format of the proprietary modelling software PowerWorld. The model covers voltages from 110 kV (a single line in the Balkans) up to 380 kV.

The 1st version was released in 2002-2004 and is no longer available (see 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 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 georef-bialek github project is an attempt to fix this.

ENTSO-E Grid Map

ENTSO-E releases maps of the European transmission grid, both electronically and in paper form.

The maps for the whole ENTSO-E system are in the projection EPSG 3034, which is a 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 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 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.

ENTSO-E Initial Dynamic Model of Continental Europe

Requires registration. Can model "the main frequency response of the system as well as the main inter-area oscillation modes".

OpenStreetMap

The global OpenStreetMap (OSM) power grid data is visible at ITO World Electricity Distribution and Enipedia has nightly extracts of the power grid from OSM.

RWTH Aachen Transmission Expansion Problem Benchmark Case

RWTH Aachen has published A Benchmark Case for Network Expansion, which is "derived from the IEEE 118 bus network and modified in accordance with European standards such as a nominal frequency of 50Hz, the use of conventional voltage levels, and conductor dimensions."

Registration is required to download the model.

The paper describing the model is A benchmark case for network expansion methods, 2015.

Typical transmission line electrical parameters

European 50 Hz transmission

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 lumped pi model.

Electrical properties for single circuits
Voltage level (kV)	Type	Conductors	Series resistance (Ohm/km)	Series inductive reactance (Ohm/km)	Shunt capacitance (nF/km)	Current thermal limit (A)	Apparent power thermal limit (MVA)
220	Overhead line	2-wire-bundle Al/St 240/40	0.06	0.301	12.5	1290	492
380	Overhead line	4-wire-bundle Al/St 240/40	0.03	0.246	13.8	2580	1698

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.

Sources for the electrical parameters:

Oeding and Oswald Elektrische Kraftwerke und Netze, 2011, Chapter 9

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).
