Maximum power point tracking using fuzzy logic controller under partial conditions
0 likes62 views
This document describes a study that proposes a fuzzy logic controller for tracking the maximum power point of a photovoltaic system under different conditions. A MATLAB/Simulink model is developed that includes a PV panel, boost converter, and fuzzy logic-based MPPT algorithm. The fuzzy controller is shown to successfully track the MPP under uniform irradiation, sudden changes in irradiation, and partial shading conditions. Simulation results demonstrate the advantages of the fuzzy logic approach over conventional MPPT methods.

The solar panel and maximum power point tracker have been modeled using MATLAB/Simulink. A simulation model consists of PV panel, boost converter, and maximum power point tack MPPT algorithm is developed. Three different conditions are simulated: 1) Uniform irradiation; 2) Sudden changing; 3) Partial shading. Results showed that fuzzy controller successfully find MPP for all different weather conditions studied. FLC has excellent ability to track MPP in less than 0.01 second when PV is subjected to sudden changes and partial shading in irradiation. KEYWORDS: 1. Fuzzy Logic Controller 2.

PV panel, boost converter with FLC connected to a resistive load has been simulated using Matlab/Simulink. Simulation results have been compared to nominal power values. The proposed system showed its ability to reach MMP under uniform irradiation, sudden changes of irradiation, and partial shading. Simulation results have shown that using FLC has great advantages over conventional methods. It is found that Fuzzy controller always finds the global MPP. It is found that fuzzy logic systems are easily implemented with minimal oscillations with fast convergence around the desired MP
