Integration of modern power generation sources along with traditional sources arouses interest at the global level, along with influence of the increasing adoption of natural gas-fired plants. This paper proposes an integrated electric power and natural gas system Mixed Integer Linear Programming model, which applies linearization techniques in order to represent both systems more realistically with a considerable reduction of computational effort. It considers effects which have not often been properly taken into account before such as hydraulic head, security constraints, water pumping, and gas effects. The Argentine Electric Power and Natural Gas Systems are selected as the test case to verify the performance of the proposed model. The power system has an installed capacity of 38 GW and 500/220 kV transmission lines with a total length of over 11,000 km. Besides, natural gas system has a injection of 120 MMm³/d and more than 12,000 km of high pressure pipelines.

现代能源与传统能源的融合，以及越来越多采用天然气发电厂的影响，引起了全球的关注。本文提出了一个集成的电力和天然气系统混合整数线性规划模型，该模型应用线性化技术，以便在减少计算工作量的情况下更真实地表示两个系统。它考虑了以前通常没有适当考虑的影响，例如液压头，安全约束，水泵和气体影响。选择阿根廷电力和天然气系统作为测试案例，以验证所提出模型的性能。该电力系统的装机容量为38 GW，输电线路为500/220 kV，总长度超过11,000 km。此外，天然气系统的注入量为120 MMm³ / d和超过12,000 km的高压管道。
