The invention discloses an electric vehicle guiding method and system suitable for an urban quick charging station, and belongs to the field of urban electric vehicle charging guiding. According to the method, on the basis of establishing an intra-area rapid charging station queue model to describe the spatial distribution condition of the electric vehicles, the stability degree of the charging station queue is evaluated through a Lyapunov function; afterwards, based on the Lyapunov optimization theory, the user dissatisfaction degree serves as a penalty function to be introduced into the optimization process, and an electric vehicle guide decision model is established by constructing a drift-penalty term function form. The model fully considers the obeying will of the owner of the electric vehicle, the charging congestion condition of the quick charging station is effectively relieved through a mode of guiding the electric vehicle, the number of electric vehicles waiting in the quick charging station is reduced, the time consumption in the charging process of the electric vehicle is reduced, and the charging satisfaction degree of the owner is improved.
本发明公开了一种适用于城区快速充电站的电动汽车引导方法、系统,属于城区电动汽车充电引导领域。本发明在建立区域内快速充电站队列模型描述电动汽车空间分布情况基础上,通过李雅普洛夫函数评估充电站队列稳定程度;之后,基于李雅普洛夫优化理论,将用户不满意程度作为惩罚性函数引入优化过程,通过构建漂移‑惩罚项函数形式,建立电动汽车引导决策模型。所提模型充分考虑了电动汽车车主的服从意愿,通过对电动汽车进行引导方式,有效缓解了快速充电站的充电阻塞情况,减少了快速充电站内部电动汽车等待数量,降低了电动汽车充电过程耗时,提高了车主充电满意度。
