摘　　要：为加强先进绝热压缩空气储能(Advanced Adiabatic Compressed Air Energy Storage,AA-CAES)与综合能源系统(Integrated Energy Systems,IES)的多能互补协同,提高系统运行效率,文中提出了一种含AA-CAES能源站的电-热综合能源系统优化运行方法。构建了含AA-CAES能源站的IES基本调度架构,详细分析了AA-CAES装置在压缩和膨胀工况下的储热、换热及供热等特性,建立了AA-CAES电热联供联储运行模型;基于热网管道传热延迟和损耗等动态特性,建立了考虑供热网储热惯性的热网方程;在此基础上,考虑了用户侧可调度资源,提出了计及综合需求响应的含AA-CAES能源站的IES日前优化运行模型;在修改的IEEE 33节点配电网和巴厘岛32节点区域供热网进行算例分析。仿真结果表明,所提方法可有效降低IES运行成本,提高IES可再生能源消纳能力。In order to strengthen the multi-energy complementary synergy between advanced adiabatic compressed air energy storage(AA-CAES)and integrated energy systems(IES),and improve the operating efficiency of the system,this paper proposes an optimal operation method of electricity-heat integrated energy system with AA-CAES energy station.Firstly,the basic dispatching architecture of IES with AA-CAES energy station was constructed.Secondly,a model of heat and power cogeneration of AA-CAES was built,and the operation characteristics of AA-CAES device under compression and expansion conditions were analyzed in detail,such as the thermal energy storage process,the thermal energy exchange process and the thermal energy provision process.Then,based on the dynamic characteristics of heat transfer delay and loss of heating network pipelines,a linear heating network equation considering the heat storage inertia of the heating network is established;on this basis,considering the schedulable resources on the user side,a day-ahead optimal operation model of IES with AA-CAES energy station in consideration of integrated demand response is proposed.Finally,the modified IEEE33-node distribution network and the Bali 32-node district heating network are analyzed by calculation examples.The simulation results show that the proposed method can effectively reduce the operating cost of IES and improve the IES renewable energy consumption capacity.
