Abstract
Many remote islands and rural communities, heavily reliant on localized energy generation, face daily challenges to meet their electricity, heat, and freshwater needs. Ensuring sustainable and secure energy and water supplies in these isolated regions is crucial but difficult, particularly due to uncertainties associated with renewable energy generation and fluctuating demands. This paper introduces a robust optimization framework featuring an integrated hybrid energy system (HES) model tailored to isolated areas and compares the performance of classical robust optimization with the Bertsimas and Sim approach. Using the Bertsimas & Sim robust optimization method, the proposed model effectively tackles uncertainties related to renewable resources like wind and solar, along with the variability in energy and water demand. This paper co-optimizes diesel generators, renewable sources, thermal units, combined heat and power (CHP) configurations, and a water desalination system by formulating a multi-carrier, mixed-integer linear programming model. Results demonstrate significant improvements in system reliability, reduced dependency on fossil fuels, and cost efficiency. Furthermore, numerical analysis shows that while both approaches enhance system stability, Bertsimas & Sim yield lower total costs and higher adaptability to unpredictable renewable output. A multi-stage sensitivity analysis validates that adjusting key robust parameters can dynamically balance resiliency with economic objectives.
