PERFORMANCE OF MATHEMATICAL MODELING OF PHOTOVOLTAIC MODULE WITH SIMULINK BUCK-BOOST CONVERTER

Photovoltaic systems require interfacing power converters between the PV arrays and the buck-boost converter. In this paper is proposes the modeling, design and simulation of photovoltaic solar cell model considering the effect of solar irradiations and changes temperature. Its voltage current and power voltage characteristics are simulated with different conditions. It is noticed that output characteristics of PV array are affected by environmental conditions and conversion efficiency is low. The use mathematical analysis is done for the single diode model. The single diode model is employed to investigate the I-V and P-V characteristics of 36 W module systems. The effect of irradiation and temperature is also considered. This mathematical analysis approach is a very flexible to change the parameters of the system.
