Research on V2G Interaction Strategy of New Power System

In view of the strategy and benefits of the interaction between the power grid and electric vehicles(EVs), the benefits of vehicle network interaction and the costs of electric vehicle interaction are analyzed respectively. Analyze the benefits generated in the process of vehicle network interaction one by one, analyze the peak shaving benefits, frequency modulation benefits, new energy consumption benefits and economic benefits generated by vehicle network interaction in detail, and establish the calculation expression of single benefit. Then the Stackelberg game model is used to carry out specific research on it, analyze the interests of both sides of the vehicle network in the interaction, and solve the interest balance point with the optimization algorithm, so as to obtain the EV charging and discharging price that balances the interests of both sides and the charge and discharge energy based on the price. Taking the use of EVs in a certain area and the load situation of power grid companies as an example, the results show that the interaction strategy can reduce the cost of electric vehicles and play a role of "peak shaving and valley filling" on the power grid load, realizing the balance of interests between the vehicle and the grid.
