| Resumo: | The accelerating global energy transition, driven by the growth of renewable energy tech- nologies, has increased the demand on the flexibility and reliability of power systems. In parallel, the integration of variable renewable sources has introduced operational uncertainty, requiring innovative solutions to ensure grid stability. Among these, energy storage systems (ESS) are emerging as vital components for enabling resilient and efficient energy networks. However, the potential of repurposing existing infrastructure, such as irrigation systems, as storage platforms remain largely untapped. This thesis investigates the feasibility of using large-scale irrigation infrastructure as a novel energy storage solution, particularly in combination with intermittent sources like photovoltaic (PV) systems. Conducted within the framework of a European project, the research focuses on modeling hybrid water-energy systems and exploring real-time opera- tional dynamics, control strategies, and optimization methods. A representative system model is developed to evaluate system flexibility and water delivery performance under fluctuating power conditions. The analysis begins with an open-loop (uncontrolled) simulation to assess the system’s natural response to step changes in electrical power. Subsequently, a closed-loop controller is implemented and tested across three operating scenarios to examine its impact on system stability, responsiveness, and tracking accuracy. The results highlight the importance of control in enhancing performance and reliability in integrated irrigation-energy systems. This work contributes to bridging the gap between energy storage integration and water infrastructure management, offering practical insights into the design and operation of resilient, low-carbon energy systems. |
