Abstract

Abstract: With growing concerns related to attacks on the cyber and physical assets associated with the power grid along with the need to mitigate impact of natural disasters, resilience has become a critical and desirable characteristic. There have been numerous efforts to define, measure and analyse resilience of smart grids. In this paper, a detailed review and comparative analysis of qualitative frameworks as well as quantitative metrics for studying resilience are provided. The desirable properties of a resilience metric are highlighted and challenges associated with formulating, developing and calculating such a metric in practical scenarios are discussed. Future research avenues in the area of developing a holistic framework for quantifying resilience are summarized with a focus on challenges related to multi-modal cyber/physical attacks, big data related issues and interdependence of critical infrastructures. Highlights: Smart grid is prone to adversarial attacks and natural hazards. A resilient grid swiftly recovers from extreme event-induced failures. Qualitative and Quantitative approaches to analyse the resilience of smart grid are summarized. Challenges arising in formulating and measuring resilience are highlighted. Opportunities for quantifying socio-technical resilience are discussed.
