摘　　要：考虑微电网MG(microgrid)与微电网聚合商MA(microgrid aggregator)的不同利益主体性,提出基于混合博弈的多微电网系统MMS(multi-microgrid system)双层优化调度模型及其求解方法。首先,分别构建上层MA与MMS间的Stackelberg博弈模型和下层各MG间的合作博弈模型,上层以最大化MA收益为目标函数,下层以最小化MMS合作联盟的运行成本为目标函数并采用Shapley值法对联盟进行利益分配。其次,上层应用粒子群优化算法求解得到内部交易电价并传递给下层,下层基于内部交易电价并利用交替方向乘子法对解耦后的各MG进行分布式优化调度。最后通过算例仿真,验证了本文所提模型的合理性和有效性。With the consideration of different interests of microgrid(MG)and microgrid aggregator(MA),a doublelayer optimal scheduling model for a multi-microgrid system(MMS)based on hybrid game and its solving method are proposed.First,a model of Stackelberg game between the MA and MMS in the upper-layer and a model of cooperative game among MGs in the lower-layer are constructed,respectively.The maximization of MA revenue is taken as an objective function in the upper-layer,while the minimization of the operation cost of MMS cooperative alliance is taken as an objective function in the lower-layer and the Shapley value method is used to distribute benefits within the alliance.Second,the particle swarm optimization algorithm is used in the upper-layer to solve the internal transaction price,which is further transferred to the lower-layer.Afterwards,the alternating direction method of multipliers is used in the lowerlayer to perform distributed optimal scheduling on the decoupled MGs based on the internal transaction price.Finally,the validity and effectiveness of the proposed model are verified by simulations of a numerical example.
