摘要
针对目标区域充电桩规划需求问题,在对区域充电需求分析和充电站数量估算的基础上,利用以同心圆的圆周和圆心为站址的充电站选址方法,构建以俘获的车流量与充电站所有成本之比最大的数学规划模型.在此基础上,根据南昌市某区电动汽车数量,确定所需要的充电站数量为4~9个,并规划出六种方案,然后对每一种方案的规划目标值进行计算和比较,得出第三种方案即建设6个充电站为最优方案.研究结果有利于完善城市的交通网络,提升城市电动汽车的运营能力.
The charging demand in the region is analyzed and the number of charging stations is estimated for the problem of charging pile planning demand in the target area.Then,the mathematical programming model with the maximum ratio of captured traffic flow to all costs of charging station is constructed using the location method of charging station with the circumference and center of concentric circle as the site.On this basis,the number of charging stations required is determined to be 4-9,and six schemes are planned according to the number of electric vehicles.So,the planning target value of each scheme is calculated and compared.The third scheme,namely the construction of six charging stations,is the optimal scheme.The research results are conducive to improve the transportation network of Nanchang City and enhance the operation ability of urban electric vehicles.
