Implementation of fuzzy logic in shunt active power filter for renewable power generation system

Shunt active power filter (SAPF) is a modern methodology for the power compensation. The primary focus of this paper is to eliminate the total harmonics distortions (THD) from the power system buses by implementing fuzzy logic control technique in the controller. This is compared with predictive control technique in the PID type controller with Non linear loads (RL, DC motor and Induction Motor). Introducing renewable power generations systems (Wind energy, solar energy) as external power supply for power compensation redefine the modern power transmission systems. Using of three leg voltage source inverter(VSI) as power converter posses less harmonics at load side compare to other converters. The voltage regulations and power quality in the bus bars is improved only after power compensations.
