    The main objective is to optimize solar energy extraction and inject maximum power into the grid while ensuring an appropriate voltage level and a frequency of 50 Hz. The studied system consists of a 100 kW photovoltaic generator, a DC–DC boost converter, and a three-level three-phase inverter connected to a 25 kV grid. The control strategy is based on a Maximum Power Point Tracking (MPPT) technique to ensure that the photovoltaic generator operates at its maximum power point, even under varying climatic conditions. Two methods were developed: the Perturb and Observe (P&O) technique and the Incremental Conductance algorithm associated with an integral controller. The boost converter adjusts the operating point of the photovoltaic panel, while the inverter, controlled through Pulse Width Modulation (PWM), generates a sinusoidal voltage compatible with the grid and reduces harmonic distortion. Simulations carried out using MATLAB/Simulink demonstrate that the proposed system improves energy efficiency and ensures stable and effective power injection into the grid while maintaining a unity power factor. The results also confirm the robustness of the adopted control strategy and highlight the importance of MPPT optimization in maximizing the utilization of the photovoltaic generator
