The invention discloses an electric vehicle charging load prediction method based on IACO-Attention-LSTM. The method comprises the following steps: selecting an electricity price and holidays as input variables; the IACO algorithm adopts an elite ant system and a minimum and maximum ant system, and when the IACO algorithm is used for optimizing the LSTM neural network, the IACO feeds back a prediction error of the LSTM neural network; before load prediction of the IACO-LSTM method, the IACO algorithm trains the LSTM, selects different hyper-parameters to train a data set and predicts an output result, determines hyper-parameters for enabling ants to traverse all targets as soon as possible according to an error between a prediction result and a real load value, outputs an optimal solution after completion of iteration, assigns the optimal solution to an LSTM neural network, and finally performs load prediction. And determining a final LSTM neural network prediction model, and integrating all prediction results by using an Attention mechanism to obtain a prediction result so as to improve prediction accuracy and efficiency.
