摘　　要：随着社会经济的发展,综合能源系统的应用越来越受到关注,但对综合能源系统灵活性的解析化动态建模尚且不足。针对这一问题,建立了一个基于区域综合能源系统(RIES)主动调节能力解析化动态评估模型。首先,通过分析RIES中多元灵活资源的多能耦合特性和调节特性,得到了RIES供需互动关系;其次,针对灵活资源的约束条件,提出了表征系统的动态灵活性的RIES可调节量评估指标,结合多能源转换、储能和需求响应等多个调控机理,从源、储能和负荷等多方面定量分别评价电力系统、热力系统、天然气系统3个系统的灵活性。最后,通过CPLEX对模型进行求解,分析负荷需求响应对RIES可调节量的影响。结果表明:负荷需求响应可以提高RIES的可调节量,证明了该模型可以有效地评估综合能源系统的灵活性、指导调度策略和优化运行。With the development of the social economy,the application of integrated energy systems has been paid more and more attention,but there is insufficient research on the analytical dynamic modeling of the flexibility of integrated energy systems.To solve this problem,an analytical dynamic evaluation model based on the active regulation capacity of the regional integrated energy system(RIES)is established.First,the interactive relationship between the supply and demand of RIES is obtained by analyzing the multi-energy coupling and regulation characteristics of the multi-flexible resources in RIES.Second,based on the constraints of flexible resources,the adjustable quantity evaluation index of the RIES is proposed to represent the dynamic flexibility of the system.Combined with multiple control mechanisms such as multi-energy conversion,energy storage,and demand response,the flexibility of the three systems of the electricity,heat,and gas is quantitatively evaluated from various aspects such as source,energy storage,and load.Finally,the model is solved by CPLEX to analyze the impact of load demand response on the adjustable capacity of RIES.The results show that the load demand response can improve the adjustable capacity of RIES,which proves that the model can effectively evaluate the flexibility of the integrated energy system,guide the scheduling strategy,and optimize the operation.
