摘　　要：计及可入网电动汽车(plug-in electric vehicle,PEV)、微电网中多种分布式电源(distributed generation,DG)输出功率的不确定性,综合考虑了DG投资、运维等成本,以及微电网带来的节能、降损、减少用户停电损失收益等因素,进行微电网电源的优化配置。PEV接入微电网后,可以根据微电网的实际运行情况作为储能装置补充原有储能元件,从而减少储能元件容量,提高微电网的经济性。从PEV参与微电网运行调度出发,建立计及PEV的微电网电源优化配置模型。算例结果表明,该模型最优解可以确保投资的最佳经济性,获得较大社会经济收益,为含PEV的微电网电源优化配置提供理论依据。With comprehensively considering plug-in electric vehicle（PEV）,the output power uncertainty of various distributed generations（DGs） in microgrid,the DG investment and operation cost,and the benefits of energy saving,loss reduction and outage loss decrease brought by microgrid,this paper optimizes the configuration of microgrid power supply.After the PEV is connected to the microgrid,it can be used as the energy storage device to supplement the original energy storage element according to the actual operation of microgrid,which can reduce the capacity of the energy storage element and improve the economic performance of the microgrid.From the aspect of PEV participating in the operation of microgrid,this paper establishes the optimal configuration model of microgrid power supply based on PEV.The results show that the optimal solution of the model can ensure the best economy of investment and obtain a larger social economic benefit,which provides theoretical basis for the optimal configuration of microgrid power supply with PEV.
