摘　　要：针对传统需求侧响应在热力系统描述方面不能满足综合能源系统应用的问题,提出了用户侧参与下的电、气、热综合能源系统联合优化调度模型。用户侧采用可转移电力负荷分类参与需求侧功率调整;综合考虑系统内部电气热的耦合及分时电价、气价等,并利用储能系统的时移特性;以调度周期内系统运行成本以及负荷调用补偿成本之和最小为目标函数,增设了考虑系统热负荷需求及电锅炉提供电力需求转换的热力平衡方程等式约束。仿真结果表明,相较于用户侧不参与调度的优化模型,用户侧的参与可改变原电力负荷曲线实现削峰填谷,同时降低综合能源系统总成本,保证综合能源系统正常运行及实现系统内源、储、荷协调互动。Aiming at the problem that the traditional demand response cannot meet the applications of integrated energy system(IES)in the aspect of thermal system description,a joint optimalscheduling model foran IES of electricity,gas,and heatwith the power user-side participationis proposed.The classifiedtransferable power load is used to participate in the demand-side power adjustment;the coupling amongelectricity,gas,and heat inthe system,the time-of-useelectricity price,gas price,etc.,are considered comprehensively,and the time-shift characteristics of the energy storage system are utilized;the minimum sum of system operating cost and the call compensation cost of loadin the scheduling periodis taken as the objective function,and athermodynamic equilibrium equation constraint that considers the system’s heat load demand and the electric boiler thatprovides power demand conversion is added.Simulation results show that-compared with the optimization model without the power user-side participation in the scheduling,the power user-side participation can change the original power load curve to achieve peak load shiftingand reduce the total cost of IES,thusensuringthe normal operation of IES and the coordinated interaction amongsource,storage,and load in the system.
