Simulation and Study of Effects of Photovoltaic System under Partially Shaded Conditions

Abstract

This paper represents the comparison between PV panel characteristics obtained under nominal test conditions and characteristics obtained during somewhat shaded circumstances. Moreover, the effects about PSC of PV panel on peak voltage and peak power are studied. The software used to study the effects is the Matlab/Simulink model. The performance parameters of the PV panel are also studied. In this paper, PV panel under PSC using a bypass diode. a model-based study is presented. In a solar PV arrangement, it is likely that partial darkness may drop over. During PSC, the PV characteristic gets added difficult with multiple peaks. PV arrangement system consists of 60 cells in sequence with to show 2 situation, However one with is no PS and one involved PS. During shading and un-shading condition, the characteristics is compared and shown in this paper. The results are shown with descriptive forms to show the results.
