Photovoltaic Cell Model Simulation in Simulink
This study develops a MATLAB/Simulink simulation model to analyze the distribution of local maximum power points in photovoltaic cells under partial shading conditions. The implementation involves creating an equivalent mathematical model of photovoltaic cells using Simulink blocks and custom MATLAB functions. The research investigates the hot-spot effects caused by shading, theoretically and experimentally validating how bypass diodes cause multiple knees in V-I characteristics and multiple peaks in V-P curves. Key algorithms include maximum power point tracking (MPPT) analysis and partial shading pattern recognition. The study focuses on predicting local maximum power point distributions under shaded conditions through derived equations, with simulation validation using PV array configurations and shading scenarios.
