随着热电联产机组、热泵、电锅炉、空调等能量转换设备的普及,电力系统和热力系统之间的能量转换和信息交互日益密切,逐步形成了电-热综合能源系统。热电联合调度可以促进可再生能源消纳,提高电力系统灵活性。首先,分析电-热综合能源系统组成,包括电网、热网和耦合设备等。在此基础上,从能量枢纽、网络拓扑和统一能路等角度回顾电-热综合能源系统建模的发展历程。然后,基于解析法和人工智能法等评述现有电-热综合能源系统优化调度研究的异同,包括考虑不确定性的电-热综合能源系统随机优化运行和热电联合鲁棒优化调度。最后,总结热电联合调度关键科学问题并对未来研究方向予以展望。

With the popularization of energy conversion equipment such as combined heat and power units,heat pumps,electric boilers,and air conditioners,energy conversion and information interaction between electric power systems(EPS)and district heating systems(DHS)have become increasingly close,gradually forming integrated electricity and heat systems(IEHS).Combined heat and power dispatch(CHPD)can promote renewable energy accommodation and improve the flexibility of EPS.First,the composition of IEHS is introduced,including electric power networks,district heating networks and coupling equipment.On this basis,the development history of IEHS modeling is reviewed from the perspectives of energy hub,network topology and energy circuit theory.Subsequently,based on analytical methods and artificial intelligence algorithms,the similarities and differences of existing research on combined heat and power dispatch are reviewed.Among them,stochastic optimal operation of IEHS considering uncertainty and robust optimal scheduling of IEHS are included.Finally,the key scientific issues of CHPD are summarized and the future research prospect are proposed.
