Abstract
This work aims to improve the performance of direct torque control (DTC) technique for induction motor based photovoltaic (PV) water pumping system (PVWPS). The innovative aspect of this work consists in introducing the adaptive fuzzy logic control and the fuzzy logic control techniques as alternative approaches to conventional DTC to control the PVWPS. To ensure a good operation of the PV array, a variable step size incremental conductance (VSS INC) is implemented. Simulation studies of the proposed topology based on intelligent approaches will be investigated using Matlab/Simulink under various operating conditions to validate the suitability of the proposed PVWPS. From the obtained results, the proposed control strategies appear to be very convenient for water pumping applications.Article HighlightsAn intelligent control based on the advanced techniques is proposed for PV water pumping system.An adaptive fuzzy logic PID approach and optimal fuzzy rules are proposed for better operation of PV system.The suggested PV water pumping system achieves better performance, in particular minimization of torque and flux ripples, reduction of torque overshoot and high dynamic response.
Highlights
Different water pumping systems use the electricity and diesel to run the pump
A comparative study of the proposed photo‐ voltaic (PV) system based on intelligence artificial techniques with the PV system based on the conventional direct torque control (DTC) (C_DTC) is effectuated
A solar PV water pumping system based on the combi‐ nation of artificial intelligence techniques is presented
Summary
Different water pumping systems use the electricity and diesel to run the pump. This kind of source has several drawbacks such as environmental pollution, low reliability, fossil fuel prices, low efficiency and high maintenance costs [1,2, 3]. It is necessary to use a sustainable and appropriate alternative source to power the water pumping systems. The use of the renew‐ able energy sources is the best solution to overcome the aforementioned drawbacks. Various renewable energy technologies such as solar, wind and biomass energies can be used for water pumping [4]. The solar photovoltaic technology is the most desired and suitable one because it is clean, naturally available and without noise [5]
