摘要:

针对综合能源系统多物理系统耦合和多利益主体参与运行的特点,为提升含高渗透率新能源的综合能源系统的能源利用率和运营效益,并计及各运行主体的运行诉求,对考虑风光出力不确定性和相关性的一主多从综合能源系统运行优化策略进行了研究。首先,提出了基于混合Copula函数理论的风光出力场景生成方法,得到风光出力的典型日场景。其次,构建面向多用户的综合能源服务商模型,并建立电、热负荷的综合需求响应模型。然后,以综合能源销售部门作为领导者,向用户发布售能价格和需求响应补偿单价;以园区能源聚合部门和储能电站作为跟随者,调节能源耦合转换装置设备出力、园区间的电能交互及储能电站充放能。最后,通过算例研究,证明该方法和策略能有效提升综合能源系统的经济效益。

Abstract:

In view of the characteristics of multi-physical system coupling and multi-stakeholder involvement in the operation of integrated energy systems (IES), this paper conducts a study on the optimization strategy of the leader-follower integrated energy systems considering the uncertainty and correlation of wind and solar output, aiming to enhance the energy utilization rate and operational efficiency of the IES with high permeability of new energy while taking into account the operational demands of various entities involved. Firstly, a scenario generation method based on mixed Copula function theory is presented to obtain typical daily scenarios of wind and PV power generation. Secondly, a multi-user integrated energy service provider model is developed and an integrated demand response model for electricity and heat loads is established. And then, the integrated energy sales department, acting as the leader, publishes energy selling prices and demand response compensation rates to users; the park energy aggregation department and energy storage stations, acting as followers, regulate the output of energy coupling conversion equipment, electricity exchange between parks, and the charging and discharging of energy storage stations. Finally, case studies demonstrate that the proposed methods and strategies can effectivey enhance the economic benefits of the integrated energy system.

Key words: mixed Copula, stackelberg game, integrated demand response, scenario generation, electrical interaction, IGDT
