Operations and Long-Term Expansion Planning of Natural-Gas and Power Systems: A Market Perspective

Natural-gas and power systems are increasingly interdependent due to the integration of an increasing number of combined cycle gas turbines in the power generation mix. However, natural gas and power systems are generally independently operated. This is the result of history and the fact that natural gas has not been important for electricity production until recently. Adopting a power system perspective, this article reviews in a tutorial manner models for the operations and long-term expansion planning of interdependent but independently operated natural-gas and power systems.
