PERFORMANCE AND MODELIZATION OF THE PHOTOVOLTAIC PUMPING SYSTEM
In this article we study with simulation in Matlab/ Simulink environment the characteristics of a PV pumping system (submersible pump case); the three parts quoted for an overview of the performance of the system, taking into account the climatic parameters (solar irradiance, and ambient temperature), and the effect of the total manometric head (HMT) on the pumped flow rate. Two mathematical motor –pump models for PV application, were proposed in this article to contribute in the studies of PV pumping sizing.Author : Mohamed Elmamy Mohamed Mahmoud, Abdellahi Ba, Ismail Bidjel Ramdhane, Yahya, A.M., Ehssein, C., Diene Ndiaye, Mahmoud, A.K. and Youm, I.
