Simultaneous charging and discharging integrating EV for V2G and G2V

Synchronization of EV to distribution grid is gaining attention as the vehicle will coordinate to distribution grid ensuring good power quality. Reduce the charging time of EV is one of the key goals in making user-friendly environment for electric vehicles. In this context, fast DC charging gives an interesting opportunity. This paper develops a Simulink model of synchronized charging and discharging of EV to distribution grid and for V2G and G2V applications, two types of converter schemes are also discussed. For making EV battery charging, the Simulink model comprises of dq frame converter control which consists of DC-DC. With this work, charging of vehicle will be fast and due to discharging of EV battery to grid, owner of vehicle will get the revenue so that overall charging price of vehicle will be reduced. Also, Two types of DC-AC converter scheme for V2G and G2V applications to find out best one on the basis of current THD analysis, prosperity of synchronization and charging-discharging control which is shown using curves of load current, source(grid) current and inverter current. Different aspects of EV's integration to grid are evaluated and better converter scheme is used in charging of EV and the results are shown.
