Study on Simulation Model of Photovoltaic Cells on Matlab/Simulink

The present photovoltaic cell simulation models present disadvantages of too many parameters and complex calculation.By using the voltage-current value of three working points under any condition,and considering the changes of working environment,an adaptive simulation model of photovoltaic cell was put forward on MATLAB/Simulink.Using the flexible solar component Ll from Uni-Solar company to make model validation,the output characteristics of the simulation model and that of real photovoltaic cells were compared under different conditions.Simulation results show that this simulation model presents less error than the solar cell module under changing irradiance and temperature.
