摘　　要：压缩空气储能(compressed air energy storage,CAES)具有多能联储/联供的特性,使其在分布式综合能源系统中具有广阔的应用前景。为加强CAES与综合能源系统(integrated energy systems,IES)的多能互补协同能力,提高用户侧能源综合利用水平,提出了一种生物质与光热耦合压缩空气储能系统的架构和运行方法。首先构建了含CAES的IES架构,通过引入生物质产生沼气,有效提升了IES供热能力。在此基础上,以系统总成本最小化为目标,提出了考虑碳交易机制和用户侧需求响应的IES优化运行方法。最后,以青海某村镇的数据进行算例分析,通过多种优化运行方案验证了所提模型的有效性和优越性。结果表明,设计工况下IES总成本下降12.4%;引入碳交易机制可以控制碳排放量下降11.3%;需求响应可以稳定负荷波动,经需求响应调整后的冷、热、电负荷峰谷差分别下降7.9%、10.9%、2.3%。Compressed air energy storage(CAES)has the characteristics of multi-energy co-supply,thus it has broad application prospects in distributed integrated energy systems.In order to strengthen the multi-energy complementary synergy between CAES and integrated energy systems(IES),an architecture and an operation method of a hybrid CAES system coupling solar thermal and biomass are proposed.Firstly,the basic dispatching structure of IES with CAES is constructed.The IES heating capacity can be improved by introducing biogas.On this basis,minimizing the operating cost of the system is taken as the goal,and the carbon trading mechanism and demand response are taken into account,so that an optimization operation model of IES with CAES is proposed.Finally,an example analysis is carried out with the data of Qinghai villages and towns,and the validity and superiority of the design model are verified.The results show that the total operation cost of IES decreases by 12.4%.the introduction of carbon trading mechanism can control carbon emissions to decrease by 11.3%,and the peak-valley differences of cold,heat and electric load after demand response adjustment can decrease by 7.9%,10.9%and 2.3%,respectively.
