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.

天然气和电力系统的运营和长期扩张规划：市场视角

由于在发电组合中集成了越来越多的联合循环燃气轮机，天然气和电力系统越来越相互依赖。然而，天然气和电力系统通常是独立运行的。这是历史和天然气直到最近才对电力生产变得重要这一事实的结果。本文采用电力系统的视角，以教程的方式回顾了相互依存但独立运行的天然气和电力系统的运行和长期扩展规划模型。
