Real-time simulation of maximum power point tracking control using fuzzy logic for stand alone PV system

摘要

This paper proposes the design of maximum power point tracking based on fuzzy logic control for standalone PV system. A complete model of the fuzzy logic maximum power point tracking for standalone PV system is compiled and loaded on the eMEGAsim using the RT-Lab real-time simulation platform from Opal-RT. The effectiveness of the proposed fuzzy logic control has been compared with the perturbation and observation algorithm in tracking the maximum power point of the solar PV array. Real-time simulation studies are carried out in RT-Lab which allows real time control and the results are presented to verify the validity of the proposed control technique. Experiment results demonstrate that the fuzzy logic control scheme provides the system with maximum power, high dynamic performance, improve tracking performance, and better control for this application.
