摘要
提出一种计及路网结构、车流信息、配电网络结构和容量约束等因素的城市区域电动汽车充电站的规划模型。该模型在配电网络的容量约束条件下,以用户在充电路程中的损耗成本和充电站线路投资之和最小为目标来进行站址和接入位置的选择,通过加权Voronoi图来实现充电站服务范围的自动划分,并利用排队论原理进行充电站的容量优化配置。最后,在兼顾电力公司和电动汽车用户双方利益的前提下,以全社会成本最小化为目标来进行充电站规划方案的优选。算例分析表明,所提出的方法和模型对于城市区域电动汽车充电站的优化规划具有一定的可行性和合理性。
Taking such factors as the road network structure,the traffic flow and the structure and capacity constraints of the distribution network into account,an optimization model for urban charging station planning was proposed.In the proposed model,the minimum sum of wastage cost of drivers on the way to charging stations and the line investment for charging stations was taken as the objective for the selection of the site and network connected positions of charging stations.The automatic partitioning of service areas of charging stations was implemented by the weighted Voronoi diagram,and utilizing the principle in queuing theory the optimization configuration of charging stations was performed.Finally,under the premise of considering interests of both power companies and electric vehicle drivers,the optimal charging station planning scheme was chosen,in which the minimization of full social cost was taken as the objective.The results of the example showed that the proposed method and model were feasible and reasonable for charging stations planning.
