Simulink Modeling, Simulation and Parameter Variation Analysis of Photovoltaic Cells

Abstract

In this paper, simulink modeling and simulation of photovoltaic cells are presented. An analysis of the effect of parameter variations is also performed on the model. Radiation change, temperature, shunt and series resistance are the parameters analyzed. Results show that when the series resistance increases in value, both the output power and the short-circuit current to decrease. A reduction in the shunt resistance was observed to cause a reduction in the output power and short circuit current. Furthermore, an increase in temperature causes a reduction in the open-circuit voltage. As the solar irradiance increases, the short circuit current increases also. It was observed generally that variations in the parameters of a PV cell affect the PV cell characteristics.
