Abstract
With the increasingly serious energy crisis and environmental problems, EV (Electric Vehicle) has become the development trend of automotive energy and environmental protection in the future. As an important supporting system for the development of EV, the charging infrastructure will inevitably affect the power quality of the distribution network when large-scale EV is put into operation. Therefore, this paper proposes an EV charging facility demand forecasting analysis method based on the charging load forecasting of the Markov model and establishes a charging facility demand forecasting model based on data fusion. Finally, the research shows that the voltage optimization of the simulated Markov model is better, but the satisfaction of the operation results of the charging pile configuration scheme before the simulated Markov model is 0.78, The operation result of the charging pile comparison planning scheme smaller than the simulated Markov model is 1.58, which indicates that the charging pile utilization rate of the charging pile comparison planning scheme simulating the Markov model is higher and the customer satisfaction is better. In this paper, Markov model is used to describe the change of the state of charge of EV users' charging piles during a day's trip, and determine the real-time charging requirements of different types of EV users.
