Power Quality Improvement for Vehicle-to-Grid and Grid-to-Vehicle Technology in a Microgrid

The demand for electric vehicles continues to grow, as evidenced by global sales of reaching 2.2 million in 2019 and more than doubling 6.6 2021. rapid growth renewable energies (EVs) necessitates the use microgrids, which are a promising solution problem integrating large-scale renewables EVs into power system. Besides, essential policy support provided government is an increase availability public charging infrastructure EVs. This research employs fast-charging configuration off-board charger with DC energy transfer. Implementation transfer vehicle-to-grid grid-to-vehicle technology microgrid due charging’s unrestricted charger-rated However, integration Microgrid system creates some operational challenges, this quality issues such harmonics systems that affect both utilities consumers. design models using PI controller fuzzy based on MATLAB software simulated determine control system’s effectiveness. These simulations assess performance, approaches help improve performance minimizing total harmonic distortion (THD). According results, logic exceeded traditional demonstrated THD also terms improving waveform achieved high accuracy good performance. utilized between microgrid, differs from other work, achieve efficiency benefit
