Large-scale and stochastic connection of electric vehicles may bring about a significant impact on the grid.Therefore it is necessary to study coordinated control strategies and rationally schedule EVs-grid energy exchanges,so as to alleviate the adverse effects of electric vehicle charging on the grid,and to utilize the energy storage characteristics of e-lectric vehicles to support distributed generation systems.This paper proposes a load balancing method for a hybrid power supply system based on V2 G technology.The method formulates charging strategies for charging stations based on the load characteristics of the grid at different time periods,which can effectively address the impact of electric vehicle char-ging on the grid,and simplify the system structure through power line carrier communication technology,thus improving system reliability.The proposed strategy and method are verified to be effective.
