    Currently, both on-grid and off-grid photovoltaic (PV) power systems are experiencing rapid annual growth, becoming a vital part of the global energy landscape. However, their performance is significantly influenced by weather conditions—particularly fluctuations in solar irradiance and elevated solar cell temperatures. This study presents the modeling and simulation of a grid-connected PV power generation system without the use of batteries, implemented in MATLAB/Simulink. The primary objective is to enhance the performance of solar energy systems through a control strategy based on Maximum Power Point Tracking (MPPT), utilizing the Perturb and Observe (P&O) algorithm, to maintain optimal operation regardless of whether variability. The PV array is initially connected to a DC-DC boost converter and subsequently connected to the AC grid through a DC/AC inverter. The inverter regulates both active and reactive power to achieve a unity power factor at the grid connection point, while phase synchronization is maintained using a Phase-Locked Loop (PLL).Simulation results confirm the effectiveness of the proposed control approach in managing power flow, ensuring the efficient delivery of maximum power to the electrical grid.
