摘　　要：从配电网潮流分析的角度出发,建立了基于电价引导原则的车网互联(V2G)功率模型。针对充电式电动汽车停车场负荷接入配电网的馈线和接入点选择问题,以减小馈线网损和日内电压波动为目标,建立了考虑V2G行为的接入规划模型。结合实例分析了负荷类型和光伏渗透率对规划方案的影响,算例结果表明电动汽车的V2G行为对配电网运行效益有显著影响,且不恰当接入方案下V2G行为可能会给配电网带来明显的负面影响。From the perspective of distribution network power flow analysis,the power model of V2G（ Vehicle to Grid） driven by electricity price is established. To address the problem of selecting the feeder and connecting point of the EVPP（ Electric Vehicle Plug-in Parking lot） load connected to the distribution network,the accessing planning model considering V2G behaviors is proposed with the objective of reducing the feeder power loss and intraday voltage fluctuation. The impacts of load type and photovoltaic penetration on planning scheme are analyzed with actual examples. Test results show that the V2G behavior of the electric vehicle has significant impacts on the operating benefits of distribution network,moreover,the V2G behavior of EVPP under inappropriate accessing schemes may negatively impact the operation of distribution networks.
