摘　　要：随着电动汽车EVs(electric vehicles)渗透率提高,电动汽车充电站EVCSs(electric vehicle charging stations)可能存在容量不足导致用户排队等待充电的情况。本文提出了一种长期利润最大化LTPM(long-term profit maximization)的充电调度策略。首先,建立了一种EVCS模型;然后,以EVCS长期利润最大化以及EV排队时长最小化为目标,提出了一种新的充电站调度算法。结果表明,与短期利润最大化STPM(short-term profit maximization)相比,采用本文所提的策略的EVCS可以获得更大的利润,且排队的EV平均延误较小。As the penetration level of electric vehicles(EVs)increases,the EVs may have to wait in queues to get service due to the insufficient capacity of charging stations(CSs). In this paper,a charging scheduling strategy of longterm profit maximization(LTPM)is proposed. First,a model for EV charging station(EVCS)is established. Then,a novel scheduling algorithm for CS is proposed,with the objective of maximizing the long-term profit of EVCS and minimizing the queuing time of EVs. Simulation results show that under the proposed strategy,the EVCS can obtain more profit compared with the short-term profit maximization(STPM)algorithm. In addition,the incurred average delays of EVs in queues are much shorter.
