摘要:
电动汽车(EV)用户对距离成本、时间成本和费用成本存在不同的偏好,在选择目标充电站时容易发生冲突;同时,不同充电站存在拥挤或空闲现象,导致单位时间盈利与设备利用均衡度较低。为此,提出了一种考虑目标充电站选择冲突的EV充电引导策略。首先,分别建立面向EV用户和充电站的快充需求模型;然后,建立EV充电冲突处理模型以及时响应用户的充电申请,减少目标充电站的选择冲突;考虑EV与充电站各自的偏好,建立双边匹配模型以实现EV充电冲突处理模型的快速求解,并得到EV充电引导策略;最后,通过实际算例验证所提EV充电引导策略的可行性与有效性。算例分析结果表明:所提策略不仅可以有效缓解充电冲突状况并均衡充电站的设备利用率,还能够有效兼顾EV用户与充电站的利益;针对不同时段的道路交通状况,所提策略均能有效适用。

Abstract:
EV(Electric Vehicle) users have different preferences on distance cost, time cost and expense cost, and are prone to conflict when choosing target charging stations. At the same time, different charging stations are crowded or idle, which leads to low profit per unit time and utilization equilibrium degree. Therefore, an EV charging guidance strategy considering the selection conflict of target charging stations is proposed. Firstly, the fast charging demand models for EV users and charging stations are established respectively. Then, the EV charging conflict processing model is established to timely respond to users’ charging applications and reduce the selection conflict of target charging stations. Considering the preferences of EV users and charging stations, the bilateral matching model is established to realize the quick solution of EV charging conflict processing model, and the EV charging guidance strategy is obtained. Finally, the feasibility and effectiveness of the proposed EV charging guidance strategy are verified by an actual example. Example analysis results show that the proposed strategy can not only effectively alleviate charging conflict and balance the equipment utilization rate of charging stations, but also effectively take into account the interests of EV users and charging stations. Aiming at the road traffic conditions in different time periods, the proposed strategy can be effectively applied.
Key words:  electric vehicles  charging stations  selection preference  selection conflict  charging guidance  two-sided matching  equipment utilization rate  road traffic
