vehicle to grid(V2G) technology has become an important means to alleviate power grid pressure
optimize energy utilization
and achieve effective integration of renewable energy. An interactive scheduling strategy for orderly charging of electric vehicles based on V2G technology is proposed. It utilizes the potential energy storage characteristics of V2G electric vehicles' bidirectional energy flow to optimize their charging and discharging behavior in different time periods
achieving the goal of reducing the total load variance and power losses of the power grid. Using the IEEE 33 node power system as the simulation environment
the simulation analysis and verification were carried out. The results showed that the proposed optimization scheduling strategy reduced the peak valley difference of the load by 27.1%
reduced the equivalent power loss by 16.4%
reduced the total charging cost by 38.6%
and controlled the number of mode switching within a safe interval of less than or equal to 3 times per day. It achieved coordinated operation and rational resource allocation between electric vehicles and the power grid
and improved the stability and economy of the power grid.
