Solar Charge Controller MPPT Simulation Model

This documentation describes a simulation model for photovoltaic arrays, incorporating both inverter components and Maximum Power Point Tracking (MPPT) technology. To enhance the tracking efficiency of boost conversion in photovoltaic systems, we developed MATLAB-based models including the MPPT initialization function (initializempptrackiref M) and the main tracking reference algorithm (mpptrackiref M). Specifically, the implementation consists of two core MATLAB script files: initializempptrackiref.m.txt containing initialization parameters and system configuration, and mpptrackiref.m.txt implementing the real-time MPPT algorithm logic. Additionally, we created the comprehensive Simulink model pv_boost_mpp_iref.mdl, which integrates the photovoltaic array with the MPPT-controlled boost DC-DC converter, simulating their dynamic interaction and control relationships. The MPPT algorithm typically employs perturbation and observation methods or incremental conductance techniques to maintain optimal operating points. Our work focuses on improving the efficiency and performance of photovoltaic arrays through advanced control strategies, addressing the challenges of modern energy requirements by maximizing power extraction under varying environmental conditions.
