Grid voltage unbalances have the potential to produce negative sequence components that disturb the control scheme of grid-tied inverters, causing current distortions and significant risks to power quality, reliability and grid safety. Main goals of the Vehicle-to-Grid (V2G) integrated model presented in the current investigation are to produce balanced currents, improve current quality, and ensure reliable operation even in the face of unbalanced grid voltages. The model includes a three-phase inverter and a CLLLC resonant converter and this model can be integrated into an On-Board Charger (OBC) system. The suggested Model Predictive Control (MPC) approach is used for the 3-phase inverter to make sure stable operation even when there are unbalanced grid voltages. The research addresses the issues caused by unbalanced grid voltages and guarantees overall improved efficiency by integrating the benefits of the CLLLC resonant converter, such as its higher efficiency, with the suggested control scheme for the three-phase inverter. Present investigation demonstrates the reliability of model in improving current quality with the least amount of Total Harmonic Distortion (THD), achieving current balance, and steady V2G operation even under challenging unbalanced grid voltage conditions. This study contributes to enhancing the V2G system compatibility with the grid, encouraging advancements in integrating sustainable energy.
