Review of Power System Resilience: Operation Stages, Vulnerabilities, and Modeling Approaches

Electricity has become a necessity of living to the extent that any outage in electric power could lead to massive disturbances in different life sectors. Natural disasters (flooding, ice storms, etc.) are considered Low Probability High Impact (LPHI) events and may lead to major power outages. Therefore, power systems must be resilient to these events to minimize the impacts of their occurrence. Studies have been presented to emphasize the importance of power system resilience and provide the power utilities and operators with different solutions and strategies to deal with this dilemma. This paper presents a review that classifies some recent power system resilience studies based on different aspects. Such aspects include the operation stages, vulnerable components, and modeling techniques. Several papers have been studied and analyzed and some future research directions have been provided at the end of the paper.
