Abstract
Rational charging service price is the key to guide the orderly charging of electric vehicles. The benefits of electric vehicle users, charging stations and power grid should be taken into account when setting service price. In this paper, a charging station service pricing model has been proposed based on tripartite game strategy. Firstly, based on the Stackelberg leadership model, the non-cooperative game model of charging station and electric vehicle users is established. Secondly, the Stackelberg leadership model is transformed into a convex optimization model using the Karush-Kuhn-Tucker optimality condition. Finally, the cooperative game model of power grid and charging station is established and the successive approximation method is used to obtain pareto optimality. Based on an IEEE 33-bus distribution network model, simulation results show that the proposed service price can coordinate the benefits of electric vehicle users, charging stations and power grid.
