Research on enhancing the resilience capabilities of power system to catastrophic disasters, characterized by low probability but high impact, is moving beyond theoretical approaches to incorporate considerations of financial and technological limitations in real-world applications. Our study aims to bridge the gap between the conceptual approach and real-world applications of resilience enhancement. This objective is achieved by developing a simplified model considering the change of resilience state that retains its original functions and characteristics, enabling the application and analysis of resilience enhancement strategies. Our study proposes a simplified model for resilience assessment that retains the essence of existing performance indices used in conventional power systems. The model incorporates the essential and non-essential demand characteristics and applies operating modes to achieve a realistic representation. The trapezoidal system state transitions were redefined based on power demand and system operating modes. The state transitions were also structured according to the defined performance indices. Availability factors were directly incorporated, while network constraints were modified and an example was constructed to facilitate model assessment. The resilience index can be readily replaced and modified by decision-makers. This will facilitate the simplified evaluation of power system resilience in comparison to critical infrastructure in other domains, providing insights from each state-specific result. |
