This paper presents an advanced Photovoltaic (PV) grid connected system utilizing a Superlift Luo Converter (SLC) to enhance energy conversion efficiency and system performance. The proposed system integrates a Crow Search Algorithm (CSA) optimized Proportional Integral (PI) controller to regulate the output of SLC. The SLC is employed to boost the voltage from the PV panels, enhancing energy extraction. The VSI, controlled by the optimized PI controller, ensures stable and efficient power transfer to the grid. An LC filter is incorporated to mitigate harmonics and ensure compliance with grid standards. The use of CSA for PI controller optimization improves dynamic response and system robustness. This results accomplished using MATLAB demonstrate that the proposed system achieves high efficiency, improved stability, and superior grid compliance compared to conventional approaches. The comparative analysis presented in this work demonstrates that the proposed approach significantly outperforms traditional methods, achieving an impressive efficiency of 95.2%. This highlights the effectiveness of the new system in optimizing performance, making it a valuable alternative to established techniques. This approach highlights the effectiveness of combining advanced converter topologies and optimization techniques to enhance PV grid connected systems.
