Fuzzy-HCC based shunt active power filter integrated hybrid energy system for compensation of harmonics

Abstract

The main objective of this study is to mitigate the current harmonic issues with the help of a suitable controller-based shunt active power filter (SAPF) in hybrid renewable energy system i.e., solar photovoltaic (SPV) and wind energy system-based distribution generation system. The SAPF is designed by using a synchronous reference frame (SRF) technique for reference current generation, a hysteresis current controller (HCC) technique for switching pulse generation and fuzzy logic controller (FLC) for DC-link voltage regulation. The suggested model of SAPF is developed in MATLAB/Simulink, and the results show that the filter performs remarkably well in supressing harmonics under different loading conditions. It is capable of providing fast corrective action under dynamic conditions and outperforms previous methods in terms of harmonic mitigation and dc-link voltage stabilization. The control techniques are compared on the basis of parameters such as harmonic compensation and dc link voltage ripple reduction capability under dynamically changing nonlinear load. The results obtained through simulation represents the validity of the performance of the filter.
