In MATLAB, implementing solar PV battery charging using Artificial Neural Networks (ANN) and Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) involves creating a sophisticated simulation environment that integrates machine learning techniques with traditional MPPT algorithms. The ANN is trained to predict the optimal operating point of the solar PV system based on input parameters such as solar irradiance and temperature, while the P&O algorithm continuously adjusts the operating point to maximize power output. By combining these approaches, the system optimizes energy harvesting efficiency and battery charging performance. MATLAB provides tools for developing and training ANNs, implementing MPPT algorithms, and simulating the entire charging process under various environmental conditions. Engineers can evaluate system performance, assess the accuracy of the ANN predictions, and refine control strategies to enhance the reliability and efficiency of solar PV battery charging systems. Through MATLAB simulations, researchers can explore innovative approaches to renewable energy integration and contribute to the advancement of sustainable energy technologies.
