A Comparative Analysis of Current Control Strategies for a Solar based Single-Phase Grid Connected Inverter

Abstract

This paper presents different current control techniques for a solar powered single-phase grid connected inverter in the application of distributed generation. The control techniques are Hysteresis controller, Fuzzy controller and Model predictive controller. The controllers are used to generate the switching pulses to the single-phase inverter. The control techniques are also achieves the unity power factor on the grid side with robust grid-current regulation. The control techniques are simulated with help of MATLAB/Simulink and their performance is compared by considering the current THD and switching frequency of the inverter.
