Abstract
In recent years, the electric power industry has benefited from decreases in natural gas prices. These low prices have encouraged the installation of natural gas-fired power plants and have increased connections between natural gas and electric power systems. However, despite their dependencies, the gas and power industries have technical, political and commercial constraints that often force them to plan, operate and manage in isolation. Such limitations sometimes lead to undesirable outcomes, such as those experienced by both systems during the winter of 2013/2014 in the northeastern United States. In this paper, we focus on reducing the technical and computation limitations. We first present a mathematical model of combined gas and power systems and apply it to planning problems where expansion and upgrades are needed to meet increased demand. We second describe our previous work in convex relaxations that have yielded promising results. Finally, we introduce a gas-price elasticity model that includes the effects of gas-price volatility caused by congestion of the integrated gas-grid expansion system.
