P&O and Fuzzy based MPPT for PV System

Abstract

The recent time has seen a massive shift in bringing renewable sources of energy into forefront. The global market has harped on producing alternative sources of energy which not only would enhance the quality but also produce sustainable source of energy. In this regard, Photovoltaic energy can be considered as a very promising renewable source of energy. This paper focuses on the very popular maximum power point tracking method which is the Perturb and Observe method. Though this method shows a good tracking response, it has some drawbacks as well. So to lower the oscillation around the MPP and to increase the speed of response, a enhanced P and O model with hybridization of Fuzzy Logic based MPPT has been proposed. The proposed method of P&O and fuzzy logic-based hybrid MPPT model has been simulated using MATLAB/Simulink and the results are presented.
