When there is an excessive amount of energy, they store it (G2V, Grid to Vehicle), and during the peak when there is an energy demand, they give it back to the grid (V2G, Vehicle to Grid). For this to work, a well-developed infrastructure and management mechanism must be set up. This paper introduces a Framework for creating a V2G and G2V system using level-3 fast charging for EVs in a microgrid. A test system for the micro-grid is built with a Charging station to connect the vehicles. The power flow in V2G and G2V is estimated by the simulations. The results show that EV batteries can actively control power in the microgrid using these modes. The charging station is designed to keep the grid current clean with minimal distortion, and the controller ensures stable DC bus voltage performance.

1.INTRODUCTION Electric vehicles play an important role in maintaining a clean, sustainable environment, as they are not dependent on fossil fuels. As their population rose, so did their vehicle numbers. Hence, energy demand should be balanced with supply. Widespread adaptation of electric vehicles. To these rising demands, DC-fast charging was presented as a solution. AC power may be stored in high-level batteries and utilized for propelling the vehicle.

Simulation packages allow engineers to study power flow, stability of the system, control measures, and the effect of high-level penetration of EVs within the grid. Modelling charge and discharge (G2V/V2G) allows for the capability of designers to study system performance under various operating conditions, as well as identify weak points in the system and identify viable solutions.
The chargers are integrated in an EVSE and are off-board for DC rapid charging. The off-board charger system has as a core component a DC-DC bidirectional converter, which can support V2G. Physical interface between the distribution grid (DC) and EV battery system. Fig.2.1 shows the converter arrangement. Converter arrangement contains two IGBT/MOSFET switches, with the complementary(control) signals applied to both switches B.
