PV-active power filter combination mitigating harmonics using FLC

Abstract

This paper proposes a Photovoltaic-Active Power Filter (PV-APF) system used in utility side. This system consists of PV panel, DC-DC boost converter with MPPT to extract maximum power, Voltage Source Converter (VSC) and Non-linear load. This PV-APF system compensates harmonic current caused by non-linear load and reduces THD% with the help of Fuzzy Logic Controller(FLC). Comparative study of PI controller and FLC based on THD% is done and the results are obtained using MATLAB/ Simulink.
