摘要

Photovoltaic pumping systems have become a key solution for sustainable water supply, especially in remote and off-grid areas. Yet, their performance often drops under changing solar conditions. To address this, we introduce Spider-Tailed Horned Viper Optimization (STHVO), a novel nature-inspired MPPT technique specifically designed for such applications. A PV generator, a step-up converter, and a radial-flow pump powered by an induction motor are all part of the suggested configuration. The system was subsequently tested under standard irradiance (1000 W/m²) and real-world irradiance variations obtained from the Bni Hadifa region. By achieving 98.92% efficiency, delivering a peak hydraulic power of 72 W, and sustaining a steady 0.65 L/s flow rate, simulation results demonstrate that STHVO performs better than traditional tactics. It also ensures rapid tracking in less than 0.6 s and constant motor speed at 195 rad/s. These outcomes show how the method can enhance solar-powered systems’ energy reliability and water delivery.
