摘要

This study introduces the Sustainability-Resilience Index (SRI), a novel metric that integrates sustainability and resilience in Hybrid Renewable Energy Systems for a petrochemical plant in Iran. Four configurations—Photovoltaic panels (PV), PV combined with Wind Turbines (PV + WT), PV with Wave Energy Converters (PV + WEC), and a combination of all three (PV + WT + WEC)—were evaluated using this index. The study reveals that when 75% weight is assigned to resilience, the PV + WT + WEC configuration scores the highest (0.90), reflecting its superior performance in resiliency-focused scenarios. Conversely, with 75% weight on sustainability, the PV + WT configuration leads with a score of 0.89, indicating its strong sustainability performance. When sustainability and resilience are equally prioritized, both PV + WT and PV + WT + WEC show competitive performance, with scores of 0.81 each. These findings illustrate how the performance of Hybrid Renewable Energy Systems configurations shifts based on the prioritization of sustainability versus resilience. The SRI allows for flexible decision-making by providing a clear comparison of configurations under various weightings. This approach not only enhances strategic planning for renewable energy systems but also supports the development of effective green energy policies at local and global levels.
