考虑通勤需求的电动汽车充电站选址与定容模型

Location and capacity model of electric vehicle charging station considering commuting demand

为满足电动汽车通勤用户在工作地点附近的充电需求,构建了以充电站建设成本和用户广义充电成本最小为目标的充电站选址和定容模型。引入了便捷系数量化用户的充电期望以得到充电站需要服务的电动汽车数量和电能需求。计算实例表明:充电站选址对便捷系数阈值不敏感,但建设经济性随便捷系数阈值的减小而变差,由此提出了不同规划目标下便捷系数阈值取值范围的建议。

In order to meet the charging demand of electric vehicle for commute users near their workplace,a charging station location and capacity model is constructed.The objectives are to minimize the cost of building charging station and minimize the generalized charging cost of users.The convenience factor is introduced to quantify the charging expectation of the user to obtain the number of electric vehicles and the power demand of the charging station.The calculation example shows that the location of charging station is not sensitive to the threshold of convenience coefficient,but the economy of construction becomes worse with the decrease in the threshold of convenience coefficient.Therefore,the range of the threshold value of convenience coefficient under different programming objectives is suggested.
