A Non-Cooperative Game Based Charging Power Dispatch in Electric Vehicle Charging Station and Charging Effect Analysis

摘要

Charging station powered by renewables combines both the renewables and electric vehicles, and has much possibility to be a key charging infrastructure. As the number of electric vehicles increase, recharging problem will become urgent and prominent. So satisfying more charging demand at same time is expected for charging station. In this paper, we present a charging station integrated with photovoltaic system/battery storage/grid-tied system power dispatch method for electric vehicles in an electric vehicle charging station, and this method based on the non-cooperative game achieves dynamically adjusting the charging power. The outstanding advantage is this method can provide charging service for all electric vehicles at the same time, especially in the situation where available charging power is limited. Comparing to the commonly used constant charging scheme, the simulation results showed that the proposed charging method can achieve higher charging service rate and higher utilization of charging pole inside charging station.
