A PV (Photovoltaic) and Wind Battery-based DC Microgrid with Perturb and Observe Maximum Power Point Tracking (PO MPPT) implemented in MATLAB is a computational model designed to simulate the behavior and performance of a DC microgrid incorporating PV panels, wind turbines, and battery storage systems. The Perturb and Observe MPPT algorithm continuously adjusts the operating point of the PV and wind systems to track the maximum power point, optimizing energy extraction. Using MATLAB, engineers and researchers can analyze various operating conditions, including changes in solar irradiance, wind speed, battery state of charge, and grid conditions, to evaluate system efficiency, stability, and energy management strategies. The simulation allows for the assessment of the microgrid's overall performance and the development of control algorithms to enhance energy utilization, grid integration, and reliability in remote or off-grid environments.
