摘要
园区综合能源系统优化运行需兼顾不同主体利益,但传统集中式优化方法难以描述各主体之间的交易互动。本文提出了一种基于源荷双侧主从博弈的园区综合能源系统运行优化策略。首先,构建了以能源供应商(源侧)、园区服务商和园区用户(荷侧)为主体的园区综合能源系统整体框架;其次,建立了3个主体的详细模型;然后,利用Stackelberg博弈方法分析源、荷两侧的能源供应商、园区服务商与园区用户之间的交易互动,并以能源供应商、园区服务商各自收益最大和园区用户综合成本最小为目标,求解源、荷双侧博弈的纳什均衡点;最后,通过算例仿真,验证了所提方法能够有效提高系统中各主体的经济收益。
The optimal operation of a district integrated energy system(DIES)should take the interests of multiple agents into account.However,the traditional centralized optimization methods are difficult to describe the transaction interaction between multiple agents.To solve this problem,an operation optimization strategy for DIES based on the game between the supply and demand sides is proposed in this paper.First,the overall framework of DIES is established with the agents of an energy supplier(supply side),a service provider,and users(demand side).Second,the three agents are modeled in detail.Afterwards,based on the Stackelberg game theory,the transaction interaction between the supply and demand sides is analyzed through maximizing the revenues of the energy supplier and service provider while minimizing the comprehensive cost of users,and the Nash equilibrium point for the game between the two sides is solved.Finally,simulations are carried out to demonstrate that the proposed method can effectively improve the economic revenue of each agent in the system.
