A novel control strategy was introduced for enhancing the performance of photovoltaic (PV) systems integrated into the power grid. The proposed method applied an Improved Grey Wolf Optimizer (IGWO) directly for Maximum Power Point Tracking (MPPT) in PV systems. The main goal is to maximize the output power extracted from the PV panels under varying environmental conditions while in the same stage improving the power quality delivered to the grid through keeping the stable voltage and frequency at the same required levels. A detailed simulation model was obtained using MATLAB/Simulink, including the PV array, DC-DC boost converter, and grid-connected inverter. The IGWO algorithm was employed to determine the optimal controlling signals for MPPT, that providing in high dynamic performance compared to traditional techniques. Simulation was included list of three cases in solar irradiance and load variations to evaluate the effectiveness of the controller. The proposed IGWO-based MPPT strategy achieved higher output power from the PV system compared to the selected traditional method as P&O. In addition, the method effectively minimized the Total Harmonic Distortion (THD) and ensures voltage with frequency stability at the point of common coupling. The designing of a single optimization control for the PV framework based on IGWO technique was the main novelty of this work through the integration between the regulated grid voltage and frequency stabilization. This control strategy enhanced the reliability, making it a strong candidate for next-generation renewable energy integration.
