A 5 MW grid-connected photovoltaic (PV) system with Incremental Conductance Maximum Power Point Tracking (MPPT) in MATLAB is a computational model designed to simulate the behavior and performance of a large-scale PV installation connected to the electrical grid. The Incremental Conductance MPPT algorithm continuously adjusts the operating point of the PV array to track the maximum power point, ensuring optimal energy extraction under varying solar conditions. By utilizing MATLAB, engineers and researchers can analyze the efficiency, stability, and grid integration of the PV system, considering factors such as solar irradiance levels, temperature effects, and grid voltage fluctuations. The simulation facilitates the optimization of control parameters and MPPT strategies to maximize energy production and grid compatibility. This approach aids in the development of reliable and efficient grid-connected PV systems, contributing to the adoption of renewable energy and sustainable power generation.
