Optimal Operation of Standalone Pv Pumping System Based on an Induction Motor

In this paper, a PV array is used for water pumping purposes at remote or abandoned locations. Egypt is a developing country and largely depends on cultivation that won’t be possible without water availability. This paper presents the performances of a PV pumping system based on an induction motor under variable solar irradiations and ambient temperatures. The Maximum Power Point Tracker (MPPT) based on Perturb and Observe (P&O) algorithm for the purpose of improving efficiency of the system is connected to the system. The main objective of this work is water pumping system, employing an induction motor pump, capable of supplying a daily average of 55 m/ hr at 20-m head has been developed. The system was installed on at western desert area in Egypt. The results presents a MATLAB/SIMULINK based modeling and simulation scheme suitable for studying the PV array under variable solar irradiations and ambient temperatures. The proposed model is very useful for PV engineers and experts who require a simple, fast and accurate PV simulator to design their systems.
