Abstract: In order to improve the stability and convergence of random-access process of charging pile load, a load random access method of intelligent charging pile based on distributed energy is designed in this paper. Firstly, the distributed energy dispatching control process is designed, then the load balancing scheduling algorithm is designed according to the charging pile demand, and the random load access is realised by planning the charging pile load boundary. Experimental results show that the load rate of each line in the power grid with charging piles is relatively balanced, and the power load output value can be stable at 36.5 kW after the application of the proposed method. Moreover, the loss function value of the proposed method gradually tends to be stable after the 100th iteration, and its value is 0.03, indicating that the proposed method has a faster convergence rate and better convergence.

Keywords: charging pile; distributed energy; load balancing dispatching; load random access.
