Differentiated Pricing Strategies of Vehicle-to-Grid Interaction with Reliable Operation of Power Distribution Facilities

Electric vehicles (EVs) are connected to the power grid by charging or swapping facilities, which can effectively exert the flexible adjustment ability of their power batteries as controllable loads or mobile energy storage, and support the construction of a new power system through integration and interaction with the power grid. In this paper, the impact of charge-discharge electricity price on the willingness of EV users to participate in vehicle-to-grid (V2G) interaction is modeled. Questionnaires or interviews are used to determine the key factors of several models, such as electric private cars, electric taxis, electric buses, and electric heavy trucks, so as to quantitatively analyze the willingness to respond to V2G interaction. Considering the reliable operation of power distribution facilities, the current situation of grid load and the transaction scenarios of participating in power grid ancillary services, the pricing strategies of electric private cars, electric taxis, electric buses and electric heavy trucks are analyzed, which can give suggestions for accelerating the development of V2G interaction to motivate EV users to participate.
