摘　　要：针对现有电动汽车充电站选址定容研究中未充分考虑用户充电体验以及未考虑充电负荷的弹性需求的问题,提出一种基于改进P-中位电动汽车充电站选址定容方法。首先,基于P-中位模型,以用户路损成本、充电站固定投资成本和运行维护成本最小为目标,建立电动汽车充电站选址定容数学模型。然后,通过松弛非线性约束,求出充电站最优选址。最后,基于改进排队论考虑充电负荷的弹性需求来优化选址定容模型,得到充电站最优容量。以某地电动汽车充电站规划进行仿真分析,验证了所建模型能够保证充电站规划的可行性和经济性。Regarding the issue of insufficient consideration of user charging experience and the elastic demand of charging load in the current research on site selection and capacity determination of electric vehicle charging stations.This article proposes an improved P-median electric vehice location and capacity determination method.Firstly,based on the P-median model,a mathematical model for the location and ca pacity dete rmination of electric vehicle charging stations is established with the goal of minimizing user road loss costs,fixed investment costs,and operation and maintenance costs.Then,by relaxing nonlinear constraints,the optimal location of the charging station is determined.Finally,based on the improved queuing theory,the elastic demand of charging load is considered to optimize the location and capacity model,and the optimal capacity of the charging station is obtained.A simulation analysis was conducted on the planning of an electric vehicle charging station in a certain area,which verified that the constructed model can ensure the feasibility and economy of the charging station planning.
