Embodiment Construction
[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0032] A method for predicting electric vehicle charging load considering time-space distribution of the present invention fully considers electric vehicle battery characteristics, charging mode, initial state of charge (SOC), traffic volume distribution and other factors.
[0033] First, according to the current travel distribution data of each traffic area, the growth coefficient method is used to calculate the predicted value of future traffic occurrence and attraction volume, and then predict the future traffic distribution among various regions; and then use the shortest path method to predict all traffic The traffic volume between the districts (i.e. OD matrix), combined with the existing road network structure information, covers all road se...
