Compensation of Power Quality using Solar-Powered Distributed Generation Interfaced by Fuzzy Logic Controlled Inverter to the Main Grid

Abstract

This paper presents a distribution static compensation (DSTATCOM) schematic for grid interconnected DG implementing solar energy to be interfaced by an inverter that uses advanced controller, which will mainly compensate power quality issues, providing active power to the grid when needed such as peak times and cutoffs, also to eliminate current harmonics at the distribution stage, in addition to compensating current unbalance at the neutral line in grids that uses three phase four wire system, the inverter involved can effectively be utilized to perform such tasks with the ability of fuzzy logic as a controller to deal with rough and sudden data, particularly when the models or the procedures are too complex to be dealt with by other controllers, which made it very suitable for this application to control the voltage of the renewable energy resources (RES) ,the Schematic is simulated using MATLAB/SIMULINK to verify the proposed outcome of this method and the results shows a fast dynamic response and high accuracy tracking the voltage of (RES) and maintained regulation to several loads variation.
