Two Level Voltage Source Grid Connected Inverter for Solar Photovoltaic System

Abstract

In the recent years, the demand for the grid connected inverters has increased immensely as they act as an interface between the photo voltaic systems and the utility. The focus of this research article is to model and analyze the design characteristics of a two level, pulse width modulated, grid connected inverter using Matlab. The Proportional Integral and Proportional Resonant controller are being investigated and the performance of these controllers is being discussed. These simulation results show that the proportional resonant controller is able to mitigate the harmonics and perform satisfactory as compared to Proportional integral controller under the same harmonic conditions.
