As an environmental friendly vehicle, the increasing number of electrical vehicles (EVs) leads to a pressing need of widely distributed charging stations, especially due to the limited on-board battery capacity. However, fast charging stations, especially super-fast charging stations may stress power grid with potential overload at peaking time, sudden power gap and voltage sag. This project discusses the detailed modeling of a multi port converter based EV charging station integrated with DC power generation, and battery energy storage system. This project analyses the capability for Plug-in electric vehicles (PEVs) in Vehicle to Home (V2H) scenarios, for which the vehicle acts as a residential battery storage system and/or a backup generator during a grid outage or more frequent short duration distribution system fault. The simulation and experimental results show that PCMM can meet the design target and verify the feasibility of the model. This charger has been implemented using a simulation analysis with a Hysteresis Control PWM technique to validate its operation. The simulation results obtained foresee an adequate interaction between the proposed charger and a compatible autonomous EMS in a typical residential setting.
