Abstract: Aiming at the increasing development of electric vehicle and renewable energy sources such as wind and photovoltaic, the structure of the comprehensive utilization for EV charging station and the RES was analyzed, and the operation mode and the profit mode of the charging station integrated with RES generation unit were discussed, then an intelligent network control system for EV charging station with wind and PV generators was proposed. Firstly, an intelligent control strategy for EV charging and discharging was proposed by taking the information of EV and power compensation amount in the charging station into account. Secondly, through analyzing the function demands of the charging station, the associate communication architecture was designed to provide strong support for the decisionmaking and carrying out of the proposed strategy and the auxiliary management function of the charging station. Finally, the numerical simulations results indicate that through the proposed intelligent network control system, both the utilization of renewable energy sources and the economy of charging station operator and EV user are improved, thus providing strong support for the charging infrastructure operation in the demonstration city.
