    Abstract: The prediction of electric vehicle     (EV) charging load, to some extent, can effectively alleviate the EV charging impact on the power distribution network. This paper proposed a kind of genetic algorithm (GA), at the same time optimized the neural network weight threshold value (connection weight) and structure, the prediction method of EV charging load for the number of hidden layer units, which was compared with the prediction method of BP neural network. The experimental results show that the proposed method has the higher prediction accuracy.
    Key words: electric vehicle; load forecasting; genetic algorithm; BP neural network
