Power Quality Improvement In A Grid Connected Renewable Energy System

In distributed system, renewable energy resources (RES) are increasingly incorporated using power electronics interfaces. Extensive use of power electronics devices generate harmonic current and may reduce quality of power. In this paper, renewable energy resources (RES) is connected to the grid through a grid interfacing inverter for power quality improvement. The grid interfacing inverter is connected to a 3-phase 4-wire system and hysteresis current control method is used to generate gate pulses. Here renewable energy resource (RES) is represented as a dc source. The grid interfacing inverter has the capability of injecting RES power to the grid and also reduces load unbalance, load harmonics and reactive power demand is compensated. Total Harmonic Distortion (THD) of the grid connected system is analyzed. The simulation has been carried out in MATLAB/Simulink.
