MATLAB BASED MODELING OF A PV ARRAY AND ITS COMPARATIVE STUDY WITH ACTUAL SYSTEM FOR DIFFERENT CONDITIONS

The paper presents the modeling of a photovoltaic array in Matlab/Simulink environment. The model is developed using basic circuit equations of the photovoltaic (PV) solar cells including the effects of solar irradiation and temperature changes. The equations of the model are presented in details. Firstly the mathematical modeling of a solar cell is done, then how a solar module, array and panel is obtained using that cell is shown clearly. Different characteristics of modeled PV panel and practical PV panel have been obtained for different parameters and comparison has been done. Solar PV panel is a nonlinear power source that needs accurate identification of optimal operating point. It is desired to operate Solar Photo Voltaic (SPV) panel at its maximum power output for economic reasons. This paper is useful to model, simulate and study the effect of changing ambient conditions of the photovoltaic arrays . The accuracy of Model is experimentally and practically verified.
