= Modelling issues =&lt;br /&gt;
&lt;br /&gt;
Compressibility, line pack (i.e. storage inside pipes), gas consumption of compressors, daily modelling, Gross Calorific Value (GCV), storage, LNG transport&lt;br /&gt;
&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;
&lt;br /&gt;

Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

Compressibility, line pack (i.e. storage inside pipes), gas consumption of compressors, daily modelling, Gross Calorific Value (GCV), storage, LNG transport&lt;br /&gt;
&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

Research at the Chair of Energy Economics at the Technische Universität Dresden addresses techno-economic questions along the entire energetic value chain, starting from primary energy production via energy conversion and transport to the final energy usage. We mainly focus on analyzing the development of European electricity and gas markets, the integration of renewable sources as well as energy and resource efficiency.&lt;br /&gt;

|text_description=The gas market model GAMAMOD is a bottom-up model used to determine and analyse the optimal natural gas supply structure in Europe and to examine the utilization of the natural gas infrastructure. In its basic version, the model includes the EU-28 countries as well as Switzerland, Norway, the Baltic States and the Balkan region. In addition, important suppliers for the European natural gas market are considered (e.g. Russia, Algeria, and Qatar). On the supply side, the model considers different production capacities with respect to the production level. The model enables the transport of natural gas by modelling pipelines and liquefied natural gas (LNG) shipping. The capacity of single pipelines between neighbouring countries are aggregated in the model. In the case of LNG shipping, the model considers regasification and liquefaction capacities in export and import countries. The model includes an exogenously imputed natural gas demand for each respective country. Moreover, seasonal demand patterns in the respective countries are considered.&lt;br /&gt;
GAMAMOD enables the analysis of trading capacities between regional markets. Due to restricted transmission capacities, regional incidences of congestions might occur. The model allows for examining supply interruptions and their impact on the European natural gas system. As each country is modelled as a single aggregated node, no congestions occur within a market area. Furthermore, the model considers natural gas storage, which ensures security of supply in the European natural gas market.&lt;br /&gt;
Cyprus and Malta are isolated from the integrated European natural gas pipeline grid. Therefore, they are not considered in the model.&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;

Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;

Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;

&lt;br /&gt;
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).&lt;br /&gt;
&lt;br /&gt;
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.&lt;br /&gt;
&lt;br /&gt;
The [http://petrowiki.org/Pressure_drop_evaluation_along_pipelines#Weymouth_equation Weymouth equation] is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.&lt;br /&gt;
&lt;br /&gt;
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:&lt;br /&gt;
&lt;br /&gt;
  f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}&lt;br /&gt;
&lt;br /&gt;
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m &amp;lt; p_n.&lt;br /&gt;
