This paper presents a three-level charging scheduling method for electric vehicle charging stations.The method entails a first-level scheduling decision which uses a GRU neural network for steering decision and region selection;a sec-ond-level scheduling planning which uses a fusion of an improved A* algorithm,a reference point hierarchy strategy,and multi-objective optimisation to provide for vehicles optimal path to reach the target charging region;and a third-level scheduling orientation which applies an improved A* algorithm to direct the vehicle that enters the target region to the idle charging pile.The proposed method facilitates improving operational efficiency of EV charging stations,mitigating char-ging-induced congestion,and promoting user experience.
