Hybrid Irrigation System in Egypt: Design and Optimization

Abstract

This presents a hybrid photovoltaic/diesel system simulated as an alternative to the diesel generators required for water pumping systems. This hybrid system is designed to overcome the limitations of the fluctuating price and availability of diesel generators, ensure a reliable supply without interruptions, and improve the overall system efficiency. The system configuration offers an economical benefits over fully renewable hybrid systems or PV only systems. The novelty of the system design lies in minimizing its complexity in terms of design size and control while using a 10 KW photovoltaic (PV) array and a 5 KW generator. The paper tackles a detailed analysis of the energy throughout the whole system, inverter design, maximum power point tracker (MPPT), and DC brushless motor are simulated. In addition, all the losses caused by rectifier, and inverter conversions are quantified. Detailed analysis of the system performance and its economical considerations are represented.
