Design And Implementation Inteligent Inverter For Grid Connected PV System

Abstract

Power generation from solar PV sources is increasing exponentially due to increased requirement of green energy. The penetration of renewable energy sources like solar Photo Voltaic (PV) and wind energy is increasing. In this study, electrical power is generate from solar energy using solar photovoltaic cell. The system is designed of PV module with associated with MPPT control DC/DC boost converters with load and connected with power grid by using 3-Φ inverter (DC-AC converter). Various control techniques are adopted to make the output suitable for controlling the converter. The Perturb & Observe (P&O) method used for the MPPT with boost converter. The PI control technique with and without Fuzzy Logic Controller (FLC) are utilized with inverter (DC/AC converter) to observe various output response and analysis of total harmonics distortion in ac output current at grid side. This study presents comparison between the PI control technique with and without Fuzzy Logic Controller (FLC) are utilized with inverter (DC/AC converter) to observe various output response and analysis of total harmonics distortion in ac output current at grid side for grid connected Solar PV system which provides a convenient choice of right technique for system.
