Abstract

Electric vehicles (EVs) emerge as a promising solution to address grid energy demands by utilizing their batteries for power storage and delivery. The concept of Vehicle-to-Grid (V2G) technology allows EVs to draw power from the grid during off-peak periods and return it during peak demand, while Grid-to-Vehicle (G2V) mode permits EVs to charge using grid supply. A bidirectional AC to DC converter and a DC to DC converter facilitate this bidirectional power transfer, ensuring efficient conversion during both G2V and V2G modes. The bidirectional AC to DC power converter rectifies AC grid supply to DC, while a bidirectional DC-to-DC buck-or-boost converter manages EV battery charging and discharging. Grid synchronization is achieved using a phase lock loop, and various controllers regulate voltage and current during power transfer. The proposed topology and control scheme are validated through MATLAB Simulink simulations, affirming the system's feasibility and effectiveness. This research provides a comprehensive framework for bidirectional power transfer between EVs and the grid, employing advanced converters, synchronization techniques, and control strategies. Simulation results underscore the viability of the proposed topology, highlighting its potential for the efficient integration of EVs into the grid and optimization of energy utilization.
