Linear models for optimization of interconnected gas and electricity networks

This presentation demonstrates a new natural gas network module implemented in the optimization model ldquoeTransportrdquo, including nodes, pipes, valves and compressors. A special linearization technique is used to keep track of the gas pressure in a generic network structure. Together with models for gas source and storage, gas-fired power plants and the existing electricity network module, the new gas module makes it possible to analyze interconnected natural gas and electricity networks where both operational and structural (investment) changes in one part of the system will influence capacities and performance in the rest of the system.
