Review of Recent Trends in Power System Resilience-Oriented Decision-Making Methods

Abstract

The recent blackouts affecting electrical grids world-wide has made power system resilience analysis one of the most relevant research topics to address in the modern power engineering literature. The main scope of this complex analysis is to assess and mitigate the grid effects of High-Impact Low-Probability events, which are typically neglected by conventional operation methods. In this context, the most challenging research directions are oriented toward the conceptualization of new methods for modeling the potential threats, predicting their impacts, and designing proper preventive and corrective actions aimed at mitigating the impacts of these threats. All these methods can be integrated into resilience-oriented decision-making tools, which represent one of the most promising emerging technology for enhancing the grid resilience against severe perturbation events. To assess the potential roles of these new methods in modern power systems, this paper presents a comprehensive review of the most relevant literature, including a detailed analysis of the threat modeling techniques, the components vulnerability models, the scenario generation methods, and the optimization frameworks enhancing resilience-oriented decision-making tools.
