电力—天然气耦合系统建模与规划运行研究综述

Research Survey on the Modeling, Planning and Operational Analysis of Electricity-Natural Gas Coupling System

随着燃气机组的广泛应用和电转气技术的快速发展,电力系统与天然气系统之间的互动日益密切,电力-天然气耦合系统是在该背景下形成的用于描述两个能源系统紧密耦合的系统形式。该耦合系统除了具有两个能源系统分别的运行特性和安全约束外,还因系统间的耦合互动产生了新的特点和约束,亟需新的分析和控制方法,近年来已经获得了国内外众多专家学者的关注和深入研究。文章从电力-天然气耦合系统的建模仿真、优化规划、运行分析(优化调度、安全评估)的角度对当前的主要研究成果进行了综述,同时总结了目前国内外学者对耦合市场的探索,最终对当前研究的不足和未来的研究方向进行了探讨。

With the widespread application of gas-fired units and the rapid development of power-to-gas(P2 G) technology, the interaction between power systems and natural gas systems is becoming more intimate. The electricity-natural gas coupling system is described as the close coupling of two energy systems. In addition to the separate operating characteristics and security constraints of the two energy systems, the coupling system presents new characteristics and constraints due to the interaction between the constituent systems. Therefore, new analyses and control methods are urgently needed. In this article, the current research on the perspective of modeling and simulation, optimal planning, and operational analysis(optimal dispatching and security assessment) of electricity-natural gas coupling systems is summarized;the current domestic and foreign scholars’ exploration of the electricity-natural gas coupling market is outlined;and finally, the limitations of current research and future research directions are discussed.
