Abstract: To control the charging load and achieve "peak shaving and valley filling" during the charging process, an orderly control method for group controlled charging load of electric vehicles is proposed. Collect parameters such as the number of electric vehicles, battery capacity of each vehicle, charging power, and charging time window, and establish a group control charging and grid connection model for electric vehicles based on the power demand function and grid power supply function. Based on the comprehensive consideration of factors such as load balancing of the power grid and the satisfaction of the charging demand of electric vehicles, load balancing is taken as the optimization objective, and a dynamic optimization objective function for group control charging load is designed. Design function constraints to constrain control objectives and achieve orderly control of charging loads. The experimental results show that the proposed method can not only achieve orderly control of group controlled charging load, but also achieve the control goal of "peak shaving and valley filling", stabilizing the charging load within the optimal range.
