Study of Partial shading Effects on Photovoltaic Arrays with Comprehensive Simulator for Global MPPT control

Abstract


The partial shading is one of the major problems that exist in the photovoltaic farm installations. This is due to the presence of multi peaks in the power curves characteristics where the conventional methods of maximum power point tracking were not able to solve the problem. To overcome this shortcoming, in the present contribution we suggest a simulator based on a tracker algorithm which is able  to track the global maximum GP in three cases , namely uniform irradiance ,sudden irradiance , and the partial shade conditions. The obtained results are compared to the data reported in the literature and showed good agreement. Thus, our simulator has been extended to include not only uniform irradiance case, but also the other mentioned cases.


Keywords
