The charging load model of electric vehicle based on cloud model

According to the randomness and fuzziness of electric vehicle, this paper determines the conception of membership by the fuzzy statistical, introduces the theory of membership cloud model and builds the electric vehicle charging load model. Respectively, this paper describes the electric car charging load in different stage, constructs the whole model of electric vehicle charging load demand and determines the range of the change of the electric vehicle charging load by cloud model. Combined with a large number of actual statistical data, the result was compared with Monte Carlo method and the accuracy of the proposed model is verified. The proposed model is suitable for all kinds of charging load prediction for specific areas and facilitates the predicted results applying in related electric cars infrastructure planning.
