面向可再生能源消纳的多能源系统：述评与展望

Abstract

打破不同能源系统之间相互分立的格局，实现多能源系统的集成与协同是解决可再生能源消纳问题的有效途径。首先，分析了多能源系统理论与方法研究框架，在此基础上从基本建模、运行优化、系统规划等多个角度评述了现有的研究并提出相应的思考。然后，将现有研究分为“以电-热耦合为主的区域多能源系统”和“以电-气耦合为主的跨区多能源系统”两个典型研究对象，综述了面向新能源消纳的多能源系统的关键研究点。最后，总结了面向可再生能源消纳的多能源系统关键科学问题，并对多能源系统未来的研究方向做了展望。

Breaking down the pattern of mutual separation between different energy systems and realizing the integration and coordination of multi-energy system (MES) is an effective way to solve the problem of renewable energy accommodation. Firstly, the research framework of the MES theory and method towards renewable energy accommodation is put forward. On the basis of the research mentioned above, the existing researches are reviewed and corresponding thinking is proposed from the perspectives of basic modeling, operation optimization and system planning. Next, the existing researches are categorized into two typical research objects which are the electric-thermal coupling distract MES and the electric-gas coupling cross-regional MES. The related key points of the research on MES towards renewable energy accommodation are reviewed and commented. Finally, the key scientific problems towards the renewable energy accommodation are summarized and the future directions of the research on MES is prospected.
