Detailed Modeling of Solar Inverter

Abstract

This paper presents the analysis and simulation of grid connected solar inverter. The system is composed of a solar panel, DC-DC boost converter, and three phase DC-AC voltage source inverter. To analyze the model, MATLAB system function (S-function) feature is used. S-function is chosen to obtain the system discrete and applicable model in real system to be able to use in an embedded system. The system mathematical equations are developed and some necessary equations are converted to discrete form to be able to adapt to system function (S-function). The system detailed model is developed and simulated by using MATLAB S-function feature. Simulated results are presented.
