摘　　要：快速充电站的布局优化需同时考虑因电动汽车续驶里程短、充电时间长等特性引起的不确定性决策问题以及长期建设过程中的连续性优化问题。由此,建立基于仿真的满足总绕行时间最短的电动汽车充电站动态布局优化模型。考虑建设时序的连续性需求,提出基于逐步优化和比较备选方案服务能力的连续性优化方法。通过实证分析探讨模型的优化布局特征和适用性。结果表明,在案例路网中应用该方法可以得到连续性较好的布局,可为快速充电站分期建设提供规划决策依据。随着充电站数量的增加,布局方案既覆盖了需求产生和通过量最大的几个节点,也缓解了因充电需求大量聚集而选择备选充电站的绕行问题。Determining the distribution of EV charging stations must consider the uncertainties in electric vehicle short driving range and long charging time as well as the long-term sustainable planning for elec-tric vehicle growth. A simulation-based dynamic layout model is developed for minimizing EV searching time for charging station. Considering construction continuity in time and space, this paper proposes a con-tinuous step-by-step optimization method that compares alternative layout plans based on the service capa-bility under different scenarios. The characteristics and applicability of proposed model is discussed through case study. The results show that a high continuity for charging station distribution at network lev-el is achieved with the optimized method, which can help to plan the construction of charge stations in stag-es. With increasing number of charging stations, the optimized scheme can both cover the nodes with larg-est charging demands and minimize EV travel time in looking for available charging stations.
