Fuzzy based Improved Incremental Conductance MPPT algorithm in PV System

C. H. Nagaraja Kumari, V.S.V Kaumudi Pravallika

Abstract

The Maximum Power Point Tracking (MPPT) is one of the significant techniques and furthermore the precise option that helps in acquiring power from the solar photovoltaic system under differing climatic conditions. This paper aims to apply an improved incremental conductance MPPT algorithm with the fuzzy logic Controller to track the Maximum Power Point (MPP) effectively. The Fuzzy controller indicates its effective viability in reducing oscillations in output with fast response under distinct temperature and irradiation conditions. In this paper, a comparative evaluation between Improved Incremental Conductance algorithm imposed fuzzy controller with that to an improved incremental conductance algorithm with PI controller, Perturb and Observe MPPT method and Incremental conductance MPPT methods can be observed under MATLAB/Simulink program environment and the proposed method shows its prominent effectiveness under various atmospheric conditions.
