摘　　要：考虑充电区间、充电速率、电池核电状态、发车策略等综合因素,提出了以最小化车辆数为目标的单线路单充电站的纯电动公交车辆调度算法。该算法采用车队整体优化的方法,使得营运的车辆数最小,并达到每辆车发车次数的均衡。以东莞松山湖公交线路为例,分析了线路发车时刻、充电速率、车辆耗电对车辆数及单车发车次数的影响,并和常规公交车辆调度算法进行比较,结果表明:改进发车策略有效地减少了所需车辆数,且车辆利用率均衡,达到了最小化车队成本的目的。An algorithm to optimize the fleet size of pure electric buses for single route and single charging station was proposed in consideration of charging range,charging rate,battery＇s state of charge and dispatch strategy etc. The algorithm utilized a global optimization method to reduce the required number of electric buses and minimize the difference among bus departure frequency. A case study for Dongguan Songshan Lake bus line was presented to test the algorithm,and the bus schedule,charging rate,the influnce of bus power consumption,on running numbers of buses were analyzed. The proposed algorithm was compared with conventional buses dispatch algorithm. It is found that the proposed algorithm can effectively reduce the required number of buses and keep the balance of bus＇ utilization rate,so that the cost of fleet operation can be optimized.
