Mathematical modeling and simulation of PV systems Part II: Simulation results

In the first part of the paper the mathematical modeling and Simulink implementation of PV systems is made. The friendly interface resulting after the simulation is similar with block libraries of the Simulink program. By using this model, the PV characteristics under different levels of irradiation, temperature, Partial Shading Conditions (PSC) can be determined easily. The second part of the paper presents the simulation results for PV systems under different atmospheric conditions. Thus, the PV characteristics under different values of irradiation (250 W/m(2), 500 W/m(2), 750 W/m(2), 1000 W/m(2)) and constant temperature (25 degrees C), under different values of temperature (0 degrees C, 25 degrees C, 40 degrees C, 65 degrees C) and constant irradiation (1000W/m(2)), and the PV characteristics under PSC are also presented.
