摘　　要：楼宇微网BMG(building microgrid)优化需兼顾提高不同主体的利益,传统优化难以满足需求,因此通过博弈论对BMG供需两侧协调优化进行研究。建立以运营商为领导者、楼宇用户为跟随者的主从博弈模型。在供能侧以运营商收益最大为目标,提出运营商灵活切换模式,并分析不同模式下供能模型选择策略,在证明Stackelberg均衡解存在性和唯一性后,采用提出的自适应差分进化算法优化供能侧。在用户侧考虑用户的综合需求响应IDR(integrated demand response),通过内部能源价格,以最大消费者剩余为目标来调整各用户用能策略。最后,通过算例仿真,验证所提方法和策略能够有效提高系统中各主体的收益。Since the optimal operation of building microgrid(BMG)needs to take into account the interests of different entities and improve the revenue of each of them,the traditional optimization cannot meet demand.In this paper,the coordinated optimization between the supply and demand sides of BMG is studied through the game theory.A Stackelberg game model is established with the operator as the leader and building users as followers.On the power supply side,with the objective of maximizing the operator’s revenue,the flexible switching mode of the operator is proposed,and the selection strategy for power supply model in different modes is analyzed.After the existence and uniqueness of the Stackelberg game equilibrium solution is proved,the proposed self-adaptive differential evolution algorithm is used to optimize the power supply side.On the user side,the integrated demand response(IDR)of users is considered,and the energy consumption strategy for each user is adjusted by taking the maximum consumer surplus as the objective through the internal energy price.Finally,simulation results show that the proposed method and strategy can effectively improve the revenue of each entity in the system.
