Abstract: With the increasing integration of electric vehicles (EVs) into the power grid, efficient bidirectional power flow management is essential for optimizing Vehicle-to-Grid (V2G) and Grid-to-Vehicle (G2V) operations. This study investigates three different control strategies for managing bidirectional power flow and improving power quality: (1) Proportional-Integral (PI) controllers on both the converter and vehicle-side battery, (2) PI controller for converter operation and bi-directional converter, and (3) FLC on both converter and the battery sides. The proposed control strategies are implemented in MATLAB/Simulink, and their performance is evaluated based on settling time, dynamic response, and Total Harmonic Distortion (THD). Comparative analysis of the simulation results demonstrates that the FLC-based approach on both the converter and battery sides provides the best performance, offering faster settling time, improved power transfer efficiency, enhanced grid stability, and reduced THD. The study highlights the effectiveness of FLC in handling system nonlinearities and uncertainties, making it a promising solution for power quality improvement in bidirectional energy exchange between EVs and the grid.
