Optimization of the Photovoltaic Pumping System Control

This paper seeks to achieve a better control and optimization between the different functions of the elements of a solar pumping system. The solar panel can provide maximum power only for defined output voltage. In addition, the operation to get the maximum power depends on the terminals of load, mostly a non-linear load like induction motor. In this work, we propose an intelligent control method for the maximum power point tracking of a photovoltaic system under variable temperature and irradiance conditions. The system was tested without MPPT, with the use of Scalar-Based control motor, but we cannot maintain the speed optimal. Next, we developed several methods for the control. Finally, we have chosen the Direct Torque Control using a Controlled Space Vector Modulation
