Recently, there has been a notable penetration of solar photovoltaic (PV) power into the grid, accompanied by a rising power demand for electric vehicles (EVs) load the distribution system. This convergence of PV and EV in the grid presents formidable challenges, particularly concerning grid synchronization during PV integration and power quality when EVs draw power from the grid. Managing the combined impact of PV penetration and EV utilization necessitates a controller capable of simultaneously addressing synchronization and power quality control. This study investigates the utilization of proportional-integral (PI) control methodologies to create an integrated controller that can effectively manage both photovoltaic (PV) and grid synchronization and address power quality concerns associated with electric vehicle (EVs) load. For PV power generation grid synchronization, a dual-control loop approach is employed, with one loop dedicated to EV battery charging control and the other focused on grid synchronization. To suppress harmonics in the grid current, the paper utilizes multicarrier Space Vector Pulse Width Modulation (SVPWM) in conjunction with PI control on the grid connected converter. The study includes the development of a MATLAB Simulink model to simulate the PV-EV-Grid setup, offering a thorough evaluation of the effectiveness of the controller. This paper contributes to the development of solutions for the challenges posed by PV integration and EV usage in the grid, enhancing the reliability and performance of sustainable energy systems.
