摘要
针对现有充电站难以满足当前不断增长的电动汽车(EV)充电需求的问题,提出一种考虑用户充电选择偏好行为的EV充电站扩容与新建规划方法。利用蒙特卡罗算法模拟规划区域内的充电需求,并基于距离分配至最近的现有充电站,获取充电需求时空分布的同时估计供需差额,确定后续扩容与新建的容量;提出基于改进Huff模型的用户充电选择偏好模型,以描述用户产生充电需求后对充电站的选择偏好行为;建立双层规划模型,上层规划综合考虑多方成本,下层规划考虑用户的相对偏好。以29节点交通网与IEEE 33节点配电网的耦合网络为算例,采用遗传算法和CPLEX求解器对双层模型进行耦合求解。算例分析结果表明所提方法具有可行性与有效性。
In response to the problem that the existing charging stations are difficult to meet the current continuously increasing charging demand of electric vehicles(EVs),a capacity expansion and new construc⁃tion planning method of EV charging stations considering users’charging preference behaviors is proposed.The charging demand within the planned area is simulated by using Monte Carlo algorithm and is then allocated to the nearest existing charging station based on distance,so as to capture the spatiotemporal dis⁃tribution of charging demand and estimate the supply-demand gap,and determine the capacity expansion and new construction of charging stations.A user’s charging preference model based on the modified Huff model is proposed to characterize users’station-selection preference behaviors after the generation of charging demands.A bi-level planning model is established,where the upper-level planning comprehensively con⁃siders multi-stakeholder costs,and the lower-level planning considers users’relative preference.Taking the coupled network of a 29-node transportation network and an IEEE 33-node distribution network as a case study,the genetic algorithm and CPLEX solver are adopted to solve the bi-level model in a coupled manner.The results demonstrate the feasibility and effectiveness of the proposed method.
