Abstract: In order to increase the short-term load forecasting accuracy of electric vehicle charging stations, the paper, according to the relevant data of a electric vehicle charging station, makes analysis of its load characteristics and main factors affecting load variation, and builds a short-term load forecasting model of electric vehicle charging stations based on the back propagation (BP) neural network optimized by artificial fish-frog leap algorithm. The simulation results show that this model has great advantages of fast forecasting speed and high forecasting accuracy. It not only suits for short-term load forecasting of electric vehicle charging stations, but also provides a theoretical basis for the next engineering practice.
Key words: electric vehicle charging station; short-term load forecasting; neural network
