Amar Neçaibia, Nadir Boutasseta, Samir Mouhajer . A Simple Theoretical Method for the Estimation of Dynamic Resistance in Photovoltaic Panels. International Journal of Computer Applications. 45, 14 ( May 2012), 21-25. DOI=10.5120/6849-9415
In this paper, we propose a simple method to determine the dynamic resistance of a PV panel directly from a current-voltage (I-V) characteristic. The information currently provided in PV panel's datasheet by manufacturers is in general insufficient to construct a mathematical model. The dynamic resistance of the PV panel is determined by simple equations and a series of experiments including simulations and field data tests. Experimental results show that the resistance-estimation method allows exact prediction of the maximum power point under various weather conditions
