Fuzzy logic based MPPT Technique for Photo-Voltaic energy conversion system

Abstract

The Photovoltaic cell is considered as one of the most promising devices in photovoltaic generation. It is used to convert solar energy into electrical energy. Nowadays, Photovoltaic generation is developing more rapidly as a renewable energy source. But, the drawback is that Photovoltaic generation is discontinuous because of it depends on the weather conditions. This paper offers an intelligent control technique for maximum power point tracking (MPPT) in a photovoltaic generation system under inconsistent temperature and solar radiation condition. This technique uses a fuzzy logic controller for a DC-DC boost converter. A photovoltaic generation system included a solar panel, a fuzzy MPP tracker, a DC-DC boost converter and a resistive load is modeled and simulate. At last compare the performance between fuzzy logic controller and Perturb and observe the method has been carried out which shown that fuzzy logic based MPPT is very effective and draw much energy and gives the fast response against any change in working conditions.
