A Novel TOU Price Based Coordinated Charging Strategy for EVs in the Fast Charging Station
Abstract
Fast charging is becoming the mainstream of electric vehicle charging mode due to its high-power rapidrecharging ability. However, it also results in a unique load with large peak-to-valley difference, which will bring new challenge to the reliable and economic operation of charging stations and even distribution networks. Coordinated charging is a promising approach to improve this load characteristic. A TOU (Time-of-use) charging pricing mechanism based on prospect theory is proposed to coordinate the charging behavior and control the charging load of the station in this paper. The gird-friendly integration and customerfriendly charging are achieved while reducing the cost of electricity purchased by charging station operators. This novel coordinated charging strategy is then studied on a case from a fast charging station to validate its effectiveness.
