摘　　要：采用Thevenin阻抗法建立计及光伏储能与电动汽车充电的节点阻抗模型,对比节点接入光伏储能装置前后电压变化,设计各个节点接入储能装置的容量,提出节点功率电压模型。最后以某小区配电网为例,应用Matlab仿真分析小区配电网接入不同比例电动汽车时的变化,仿真结果表明电压波动减小39%,储能容量减小14.7%,网络损耗减小26%,验证了控制策略的有效性和可行性。The paper establishes node impedance model considering photovoltaic（PV）energy storages and electric vehicle（EV）charging by using the method of Thevenin impedance analysis.Comparing the node voltage deviation before and after PV energy storage integration,the paper designs the capacity of integrating energy storage on each node,and gives node power-voltage model.In the end,taking the distribution network in a residential district as an example,the paper carries out the simulation analysis on the node voltage fluctuation by Matlab.The results show that the voltage fluctuation is reduced by 39%,the storage capacity is reduced by 14.7%and the loss of the distribution network is reduced by 26%,which verifies the effectiveness and feasibility of proposed strategy.
