As energy storage equipment in micro grids, the electric vehicle (EV) battery can be used. When the energy supply of granny-to-vehicle and G-V (Vehicle-to-Grid, V-G) exceeds the grid, and when demand is made available there is power supply back to the grid, micro grid energy control can be useful. In order to apply this technique, appropriate infrastructure and control systems need to be established. This report contains the design to create a V-G to G-V micro-grid system using fast charge of the EVs level 3. An EV interface micro-space testing system is modelled with a rapid loading station. Coordination is the control over the charging pattern of different EVs and their relative battery status in response to the present grid conditions. Good coordination between EVs is therefore needed to stabilise the grid. In light of the increased penetration of EVs, the vehicle-to-gage idea (V-G) can be researched in order to send the additional energy in controlled form back into the grid. Battery energy from EVs can be discharged into the grid as a distributed energy storage method by V-G in collaboration. The voltage profile at distribution nodes may be flattened if EVs are charged in a coordinated manner. A typical city distribution system is designed to exhibit V-G capacity, For example, high demand and reduced voltage. The simulation of the V-G distribution system is tested using the logic controller (FLC). In both the loading station controller and the V2G controller, two controls have been incorporated into the system. On the flow of electricity from the EVs to the grid, a collective decision is made. According to the real scenario in terms of energy or time required for the charge the power output of the EV network is being handled and tested.
