摘要

As the world clamps, renewable energy and the popularity of Electric Vehicles (EVs) grow, there is an increasing need for highly developed power conversion systems that incorporates with PV and EV infrastructure. For successful integration this research proposes a comprehensive power management and control architecture for Photovoltaic (PV) based energy system integrated with battery storage and grid connectivity. The system is configured with a novel Z-Source integrated Coupled Inductor Single Ended Primary Inductor Converter (ZS-CI-SEPIC), combining the advanced features of both Z-source networks and coupled inductor SEPIC topologies to improve the PV array efficiency, delivering power directly to the grid. It integrates Osprey Optimization Algorithm (OOA) for tuning Proportional Integral (PI) controller of PV, resulting in stabilized DC bus voltage regardless of solar fluctuations. This controller optimizes the control parameters to achieve stable and efficient operation under varying conditions, maximizing the performance and reliability of PV-based EV charging system. In addition, grid is incorporated, for utilization of power during times of power demand or insufficient supply from PV system. By utilizing PV to charge EVs and perfectly integrating it into grid, this approach not only promises to reduce carbon emissions but also enhances energy efficiency and resilience. The validation of proposed system is examined using MATLAB and the outcomes reveals improved converter efficiency of 97.14%, signifying enhanced voltage gain with minimized loss while conversion. Furthermore, the proposed converter maintains a steady voltage, even under changing condition together with the support of OOA-PI controller. The Total Harmonic Distortion (THD) values below 1% in simulation and 3.47% in hardware (R-Phase) ensuring high quality power delivery. These outcomes establish the superiority of the developed topology in ensuring efficiency and power quality in PV-EV charging system.
