An intelligent novel FLC based FOINC MPPT technique for PV applications

Abstract

This Harnessing energy from the abundant and free sunlight is now a days a hot-topic among the research community. The availability of cheap solar modules has made it possible to harvest solar energy with better efficiency. The nature of solar modules is nonlinear and therefore the process of impedance matching is essential. The proper impedance matching ensures extraction of the maximum power from solar PV module. Several algorithms are reported in literatures that are used to operate the DC-DC converter around MPP. Among those algorithms online techniques are most efficient and easiest to implement. However, the offline techniques are simple but power in loss. In this paper proposed a modified FLC based FOINC algorithm for online MPPT technique. The proposed technique deals with intelligent about measurement of voltage and current. The technique is modeled and simulated in MATLAB/Simulink environment and the results shows satisfactory performance against test conditions.
