The batteries of in micro grid, electric vehicles (EVs) can function as storage units. As EVs provide grid-to-vehicle (G2V) energy, they can potentially benefit micro grid control of energy through energy storage and supplying back to the grid when needed. There are 3 levels of charging, in which Level-1 has 120v outlet. It is the slowest charging process and runs less than 60kms a day and need to charge all the night. Electric vehicle supply equipment is used during Level-2 charging (EVSE) and it can supply power at 220 volts (or 240 volts) up to 30Aand time taken for charging is 6hours. A further problem is that energy cannot flow via the distribution grid in both directions. Level-3 charging circuits also known as DC fast charging circuits are used, which can provide energy up to 90kw and lowering the charging time to 20–30 minutes at 200/450v. The charging circuits used in this project are OFF-Board charger switch use a special topology of a buck-boost Converter. For the purpose of establishing a V2G architecture on a DC micro grid rapid charging is proposed. Power that moves in both directions transmission the grid and EVs are separated by made possible via a power electronic inverter interface. The MATLAB software has been used to evaluate the V2G and G2V modes of operation.
