Matlab/Simulink simulation research on a simplified mathematical model of PV cells

A simple and practical mathematical model of PV cells and a simple estimation method of PV cells' series resistance are researched and proposed.The model only need two parameters of PV cells--Uocref and Iscref can meet the demand of engineering simulation.The Matlab/Simulink is utilized to simulate the mathematical model and draw the corresponding curves,the study results show the PV cells' mathematical model researched in this paper is simple and practical.
