On the resilience of modern power systems: A complex network perspective

This paper provides a compressive literature review on the application of complex network theories in the resilience evaluation and enhancement of modern power systems. First, the resilience property is decomposed into structural and operational aspects. On one hand, the structural resilience is explained and reviewed by modeling modern power systems as graphs and analyzing the pertinent static and dynamic characteristics. On the other hand, after converting operational data to certain networks, the operational resilience is investigated throughout the progression of an extreme event, namely, from preventive, corrective, to restorative strategies. Moreover, the discussion on resilience evaluation and enhancement is extended to multilayer networks as modern power systems are increasingly coupled with communication networks and other energy carriers. It is concluded that complex network theories serve as an effective means to comprehending and refining the structural and operational resilience of modern power systems.
