Design and Analysis of a Novel Fuzzy Logic Controller Based AFLL Topology for Grid Connected PV System

Authors(2) :-Thalla Bharathi, Dr. I. Prabhakar Reddy

This research provides an advanced frequency locked loop (AFLL) architecture for grid-connected PV systems that is based on fuzzy logic control (FLC). The FLC's interlinking with AFLL offers grid-connected PV systems both advantages. One artificial intelligence technology that offers fast reaction to system disruptions is the FLC. The proposed grid-connected PV system's performance is enhanced by the FLC-AFLL control architecture across a variety of disturbances, including polluted grid conditions, fault conditions, and load shifts. This suggested design would lessen harmonics in grid-connected PV systems and decrease load current disturbance. By injecting/absorbing active and reactive energy into grid-connected PV systems, FLC-AFLL control architecture enhances power quality in a long-distance radial transmission system. The entire proposed system performance is tested by using MATLAB/SIMULINK software.
