This research proposes a comprehensive three-phase grid integration system incorporating solar energy through a bidirectional buck-boost converter topology. The photovoltaic (PV) array output undergoes a boosting process via the bidirectional DC-DC converter, with control facilitated by the Maximum Power Point Tracking (MPPT) technique for optimal power extraction. The grid and PV array operate in parallel, ensuring a continuous power supply to electric vehicle (EV) batteries. The study advocates for utilizing EV batteries as energy storage units in microgrids, employing Grid-To-Vehicle (G2V) and Vehicle-To-Grid (V2G) strategies to manage energy surplus and deficit. The paper underscores the importance of establishing infrastructure and control mechanisms for effective implementation. The research delineates the architecture of EV battery charging within a V2G-G2V system on a microgrid, demonstrating power transfer through simulation. Test results reveal that EV batteries actively regulate microgrid power dynamics using G2V-V2G operating modes. The proposed controller exhibits enhanced dynamic performance in terms of DC bus voltage stability, and the charging station design mitigates harmonic distortion in grid-injected current.
