You have full access to this open access article In recent years, the integration of bidirectional converters in the grid for V2G (vehicle-to–grid) applications of Electric Vehicles (EVs) has gained significant attention due to its potential to enhance grid stability, energy efficiency, and economic benefits.
The V2G architecture allows EVs to feed electricity back to the grid during peak load periods and draw power from the grid during off-peak times, thus achieving the goal of peak shaving and valley filling .
The EV is charged during night hours when electricity demand is low, and when it has sufficient charge in the day, it can discharge some of its energy in the evening when power demand is high. As V2G has advantages, there are also drawbacks like impact on battery depreciation, complex control mechanism, etc.;
