资金约束下单向共享电动汽车系统的充电站选址

Charging Station Location of One-way Shared Electric Vehicle System under Financial Constraints

针对单向共享电动汽车系统提出了一种充电站位置优化的方法,充电站的容量和服务范围内的需求量相适应;该方法基于混合整数规划模型,其目标考虑了满足服务的收入,车辆折旧成本和充电站的充电桩运行成本,目标函数为最大化共享电动汽车服务商的利润.最后进行了模拟仿真来测试方法的松弛度和性能,模型能够在合理的时间内解决较大规模的问题.

A method for optimizing the location of charging stations is proposed for the one-way shared electric vehicle system, with the consideration of rational capacity of charging station and the demand within the served area. Thus the problem of unbalanced vehicle inventory is solved and the customer demand is satisfied to the maximum. The method is based on the mixed integer programming model. The goal is to meet the revenue of the service, the operating cost of the station, and the depreciation cost of the vehicle. The objective function is to maximize the profit of the shared electric vehicle service provider. Finally, simulations are carried out to test the slack and performance of the method, and the model can solve large-scale problems in a reasonable time.
