A Fuzzy Based PV-APF Controller For Compensating Current Harmonics

Abstract

The main aim of this paper is to compensate a current harmonics in PV-APF system using Fuzzy Logic Controller. A 3- Ф 3-wire system is proposed in this paper which consists of PV system, a dc/dc converter which is controlled by MPPT, three phase VSC to act as APF and Non-Linear Load. The main theme of this INC MPPT is to efficiency from the PV system. For reliable performance of active power filter and better harmonic compensation this paper propose a concept of instantaneous power theory. Also, a comparison analysis is performed for improving THD by PI/Fuzzy controllers. The proposed system is simulated and verified in MATLAB/SIMULINK software.
