综合能源系统(integrated energy system,IES)是未来能源消费方式的重要发展方向,对提升能源的综合用能能效和可再生能源的消纳将发挥越来越重要的作用。然而,由于IES中能源系统的高度耦合以及源-网-荷-储各个环节存在的不确定性,使得IES的动态过程极其复杂,给IES的优化运行带来巨大挑战。针对IES的优化运行问题,首先简要介绍了IES的概念,分析了其主要特点;其次总结和概括了IES运行基础信息感知、混合时间尺度动态协调优化调度体系及其求解算法三个方面的国内外研究现状,并指出了现有研究的不足之处;最后展望了IES优化运行未来的研究方向,为该方向的后续研究提供参考。

Review of Research on Optimal Operation Technology of Integrated Energy System

Integrated energy system (IES) is an important development direction of energy consumption in the future, and will play an increasingly important role in improving the energy efficiency of integrated energy use and the consumption of renewable energy. However, due to the high coupling of energy system in IES and the uncertainty in each link of source-network-load-storage, the dynamic process of IES is extremely complex, which brings great challenges to the optimal operation of IES. This paper aims at the optimal operation of IES. Firstly, the concept of IES is introduced and its main characteristics are analyzed. Secondly, the research status in home and abroad on the basic information perception of IES operation, the dynamic coordinated optimization scheduling system with hybrid time scales and its solution algorithm are summarized, and the shortcomings of the existing research are pointed out. Finally, the future research direction is prospected. The results of this paper will provide a reference for the follow-up research of integrated energy system.
