电动汽车充电站规模优化模型研究

在考虑电动汽车顾客流量按一定比率增长的情况下，以年平均系统成本最小为优化目标，建立一个电动汽车充电站规模优化模型。针对这一非线性整数规划问题，采用分支定界法进行求解，得出每个规划周期内充电站和充电机的最优配置数量，并运用算例验证了该模型的合理性和有效性。  

Research on the Optimal Scale Model of the Electric Vehicle Charging Station

We develop an optimization model to minimize the average system cost per year under the situation that the demand of electric car is increasing at a certain rate. For the nonlinear integer programming problem, branch and bound method is used to solve the optimal amount of the charging stations and the optimal number of charging generators at each station for every planning horizon. And a numerical example is provided to demonstrate the validity and effectiveness of the model.
