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.

Simulink model for asynchronous motor control based on Chen Boshi's theories, covering power electronics and motion control. Power electronic converters have transitioned from thyristor-based controlled devices to power switching devices, shifting control technology from phase control to PWM (Pulse Width Modulation). Analog electronic controllers have been largely replaced by digital electronic controllers, while AC adjustable-speed drives have progressively superseded DC drives. Significant advancements continue in AC drive control technologies, with modern implementations leveraging MATLAB/Simulink for algorithm development and system simulation.
