中文摘要：

针对电动汽车充电站的选址问题,在现有的选址模型的基础上加入充电站服务容量的因素,并将服务容量延伸为充电站充电桩的数量和用电配额两方面,建立了一个新的充电站选址的整数规划模型。该模型的目的是在满足各个地点的电动汽车对电量需求的前提下,最小化充电站建设总成本。接着,将模型应用到湖北省高速公路网电动汽车充电站建设规划的案例中去,通过对模型的求解来对该地区的充电站的选取与规模的大小进行分析,给出湖北省高速公路网充电站建设规划的解决方案。最后,针对车辆的最大行驶范围和安全电量水平两个参数来对模型进行了敏感度分析,发现行驶范围和安全电量水平是影响充电站建设的重要因素。

英文摘要：

This paper studied the problem of locating electric vehicle refueling stations.Based on the existing models,we purposed a new model using an integer programming method which took service capacity of refueling stations in to consideration.The aim is to simultaneously serve intercity and intra-city travel and minimize the construction cost while satisfying demand of electric power from refueling stations.The model divided the service capacity into two parts：the number of charging point and the maximum electricity available.A numerical example using freeway network in Hubei province of China was given.We analyzed the result and drew conclusion about the characteristic of station selected.Some sensitivity analysis about this model was showed.Two factors are mainly considered：the maximum range and the safety electric quantity remained of EV,and the results under different conditions.The result showed that two factors had a great effect on the number of stations and the construction cost.Based on the noninferior solutions,decision makers can thus better formulate viable station-deployment plans.
