The invention belongs to the technical field of electric vehicle charging load prediction, and particularly relates to an electric vehicle charging load spatio-temporal distribution prediction method based on information physical fusion, which comprises the following steps of: generating parking duration, initial travel time, initial electric quantity, starting point position and terminal point position of a single electric vehicle; according to the method, the shortest travel path of the electric vehicle is obtained through shortest path planning, then the farthest drivable distance of the electric vehicle is calculated based on the remaining electric quantity when the electric vehicle generates the charging demand, then the final charging node is determined, and the shortest charging path is obtained through the shortest path planning. And then calculating the remaining capacity of the battery and the queuing waiting time when the electric vehicle arrives at the final charging node, determining the final charging node, the charging starting time and the charging power of the electric vehicle, and finally outputting a dynamic prediction result of the charging load spatial and temporal distribution of the electric vehicle. The method can improve the prediction precision of the dynamic prediction result of the time-space distribution of the charging load.

    本发明属于电动汽车充电负荷预测技术领域,具体涉及一种基于信息物理融合的电动汽车充电负荷时空分布预测方法,方法先生成单辆电动汽车的停车时长、初始出行时间、初始电量、起点位置、终点位置,通过最短路径规划获得电动汽车的最短出行路径,然后基于电动汽车产生充电需求时的剩余电量计算电动汽车的最远可行驶距离,进而确定最终充电节点,通过最短路径规划获得最短充电路径,再计算到达最终充电节点时的电池剩余电量与排队等候时长,进而确定电动汽车最终充电节点、开始充电时间以及充电功率,最终输出电动汽车充电负荷时空分布的动态预测结果。本发明能够提高充电负荷时空分布动态预测结果的预测精度。
