Improving photovoltaic water pumping system performance with ANN-based direct torque control using real-time simulation

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Feb. 2, 2025

Abstract Photovoltaic Water Pumping Systems (PVWPS) have become increasingly important as a renewable energy solution in rural areas, providing independence, cost savings, and environmental friendliness. This system has two main controllers. The first controller is employed to maximize power extraction from the PV array by controlling duty ratio of DC-DC boost converter. second responsible for regulating operation induction motor through switching pulses Voltage Source Inverter (VSI). These controllers play an essential role system, which increases efficiency performance. Therefore, innovative aspect this work consists introducing Artificial Neural Networks (ANNs) based on each PVWPS controller. On one hand, ANN-based MPPT implemented ensure optimal performance under varying irradiation levels. other overcome defects problems caused Direct Torque Control (DTC), such flux torque ripples, high frequency, challenges at low speeds, DTC proposed hysteresis comparators, table, speed are replaced ANN controls thoroughly modeled simulated using MATLAB/Simulink software validated dSPACE DS1104 Board. results demonstrate significant improvements, including 75.51% reduction 77.5% 44.79% improvement response time, increase water quantity. Furthermore, Real-Time simulation visualization obtained consistent with outcomes.
