由于经济、环境和技术的变化，在过去二十年中，用于发电的天然气（NG）的消耗迅速增长。这导致了天然气和电力系统之间的强烈相互依赖。研究表明，在电力系统运行中考虑天然气输送后，总的运行成本大大降低。由于压缩机站的燃料消耗在天然气输送成本中起着重要作用，天然气输送成本占总成本的75%。本文介绍了一种考虑二次燃料的两系统联合运行的新方法。天然气和电力系统的静态潮流方程建模为一个优化问题，重点是压缩机站的角色。目标是使两个系统的总运行成本最小化。呼罗珊省天然气和电网的仿真结果表明，成功的电厂燃料管理和两个系统的总成本大大降低，特别是在高峰状态。
Due to economic, environmental and technological changes, consumption of Natural Gas (NG) for electricity generation has burgeoned over the last two decades. This has led to strong interdependency between NG and electricity systems. Studies indicate a great reduction in total operating cost after considering NG transmission in power system operation. As Fuel consumption of compressor stations plays a major role in the NG transmission cost which constitutes of up to 75% of the overall expenses. In this paper a novel approach to integrated operation of two systems with consideration of 2nd-fuel is introduced. Static load flow equation of NG and electricity system is modeled as an optimization problem with focusing on compressor station roles. The aim is to Minimized total operating cost of both systems. Simulation result of Khorasan Province NG and electricity Network show success in power plant fuel management and great reduction in total cost of two systems especially in peak condition.
