Intelligent Management of the Pumping System for Irrigation of MBAWAANDE Lands in Podor within the NANN-K Project

Abstract

This article addresses the constraints in exploiting the "MBAWAANDE" lands, particularly the challenges posed by their irrigation system. Currently, the system is powered by a diesel motor pump and a photovoltaic solar system located far apart, leading to inefficiencies and operational difficulties. To mitigate these issues, we propose replacing the motor pump with a generator mounted in parallel with the photovoltaic solar system. This new hybrid configuration, automated by an algorithm, aims to reduce the operational constraints related to distance and minimize diesel consumption, while ensuring continuous and reliable irrigation. The hybrid system integrates the strengths of both power sources, allowing for more flexible and sustainable water pumping. The diesel generator provides backup power during periods of low solar irradiance, ensuring that irrigation needs are met without interruption. Meanwhile, the photovoltaic system takes advantage of renewable energy, reducing dependency on fossil fuels and lowering operational costs. To validate the efficiency and effectiveness of this new configuration, we conducted a simulation using Matlab/Simulink. The results demonstrated that the hybrid system significantly enhances water pumping efficiency with minimal human intervention, ensuring a steady water supply for irrigation. These findings highlight the potential for hybrid systems to improve agricultural practices, especially in remote and resource-constrained areas.
