Controllable Bidirectional Power Transfer between Electric Vehicle and Grid at Different Loading Condition with Solar Power

Increasing number of plug-in electric vehicles (PEV) increases the need of fast charging station thus creating burden on current grid system. Installing charging stations can perform specific tasks, which will reduce the burden on the grid and help the system to maintain power balance for longer duration of time. This paper proposes the power-balancing configuration of photovoltaic (PV) array, storage unit of electric vehicle, and the grid. The power circuit comprised of bidirectional converter, class C type chopper acting as charging and discharging circuit, battery, load, and switches. The computer simulation results obtained proposes the power synchronization between the grid, battery and PV power at different loading conditions, different solar irradiance conditions and different grid power availability conditions.
