Fuzzy Controlled Based PV Three Phase Inverter For Grid Connected System

Abstract

Distributed Generation (DG) is presently broadly utilized in numerous power age systems. It is generally in light of sustainable power sources and vitality stockpiling, for example, photovoltaic cells (PV), wind turbines (WT) and energy components to limit contamination and ozone harming substance emanations. For expansive scale establishments, a three stage control electronic inverter used to interface the wellspring of sustainable power source to the utility network. The related control framework and inverter are at the center of the vitality change process and their task is basic for low consonant contortion and to infuse high power quality current to the matrix. Consequently worldwide consonant and power quality proposals, for example, IEEEStandard519and1547,are often in place to limit the harmonic currents injected into the grid. Typically, 5% current total harmonic distortion (THD) limit is imposed. A Fuzzy controller is also implemented in this project in order to reduce the THD. In addition, the fuzzy and adaptive PR controller offers superior output power regulation, and improved power quality performance. Results are analyzed through MATLAB/SIMULINK environment.
