Photovoltaic Solar Water Pumping by Predictive Control of Induction Motor

Abstract

The advantages of using the photovoltaic system for water pumping are easy assembly and installation of components, low maintenance and noise-free operation. This paper deals with the design and control of photovoltaic (PV) system interconnected with a three-phase voltage source inverter (VSI) and a motor-pump assembly. this work also focuses on demonstrating the efficiency and performance of Predictive control (FS-MPC). An incremental conductance (InC) modified with the flow-rate power control is proposed to exploit maximum power from a PV array, which is eligible to regulate the flow rate corresponding to desired flow ,  high gain observer (HGO) has been utilized to estimate the mechanical and magnetic states , which uses only the measured stator currents and control voltage.  Results of simulation studies demonstrate that robustness and efficiency of the system are maintained under any insolation level.
