摘　　要：能源结构的多元化趋势以及可再生能源与负荷的频繁波动,对综合能源系统的稳定运营造成巨大威胁。提出一种在绿证碳交易下考虑系统灵活性的源荷协调优化调度方法,在供能端引入有机朗肯循环技术,利用余热进行发电,从而摆脱热电联产机组传统上“以热定电”的限制,提高热电联产机组灵活性能力以及热电需求响应交互能力;考虑系统负荷和可再生能源的波动性和不确定性,构建了灵活性需求模型。为提升可再生能源消纳和降低碳排放,引入绿证碳交易机制,结合系统灵活性需求的源荷协同优化调度策略,设计了四种不同方案进行模拟验证,提升了系统经济性和可再生能源消纳能力。The diversification of the energy structure and the frequent fluctuations in renewable energy sources and loads pose a great threat to the stable operation of the integrated energy system.This paper proposes a source-load coordination and optimization scheduling method considering the flexibility of the system under the green certificate carbon trading,and introduces the organic Rankine cycle tech-nology at the energy supply end to use waste heat for power generation,so as to get rid of the traditional limitation of“heat to determine electricity”of cogeneration units,and improve the flexibility of cogeneration units and the interaction ability of heat and power demand re-sponse.Considering the fluctuation and uncertainty of system load and renewable energy,a flexible demand model is constructed.In order to improve the consumption of renewable energy and reduce carbon emissions,the green certificate carbon trading mechanism was introduced,and four different schemes were designed for simulation and verification based on the source-load coordination and optimal scheduling strat-egy required by the flexibility of the system,which improved the system economy and the capacity of renewable energy consumption.
