“…In the current study, we define "adaptation" as the process of changing to make the system suitable for a new situation and "recovery" as the process of returning to a normal condition after a period of disturbance. On the basis of this observation, we define resilience as "the ability of a system to adapt to disaster scenarios and recover to pre-disaster states" (Huang et al, 2017). This definition is concise but reflects both features that all the different definitions share and is applicable to not only power grids but also systems in other disciplines.…”

“…In our previous work (Huang et al, 2017), we minimized the total load shed to enhance power grid resilience because the system resilience was quantitatively measured by the total load served. The larger the served proportion of the total load demand, the smaller the shed proportion of the total load demand and the higher the resilience of the system.…”

“…To make the grid strong and smart against disasters, the concept of power grid resilience was introduced and has soon attracted much attention around the world. According to our previous work on power grid resilience (Huang et al, 2017), system resilience enhancement strategies can be categorized into resilience planning, resilience response, and resilience restoration. The milestones of resilience enhancement strategies are depicted in Fig.…”

“…Considerable prior work has focused on resilience planning; however, system operators must also consider options to enhance power grid resilience from the perspective of operation, because operational strategies as "smart" measures can provide more specific and therefore more cost-effective strategies than resilience planning (Huang et al, 2017;Panteli et al, 2017b). These operational strategies are collectively called "resilience response" (Huang et al, 2017).…”

“…Adapting to the 21st century, our critical infrastructure is facing rapidly growing uncertainty and therefore becoming vulnerable to not only natural disasters (e.g., hurricanes and flooding) but also man-made disruptions (e.g., human errors and terrorist attacks). As a result, the concept of resilience is recently introduced into critical infrastructure systems (Tierney and Bruneau, 2007;National Infrastructure Advisory Council, 2009;White House, 2013;Panteli and Mancarella, 2015a;Wang et al, 2016a;Huang et al, 2017).…”

Boosting the resilience of power systems is a core requirement of smart grids. In fact, resilience enhancement is crucial to all critical infrastructure systems. In this study, we review the current research on system resilience enhancement within and beyond smart grids. In addition, we elaborate on resilience definition and resilience quantification and discuss several challenges and opportunities for system resilience enhancement. This study aims to deepen our understanding of the concept of resilience and develop a wide perspective on enhancing the system resilience for critical infrastructures.

Summary To enhance the resilience of distribution systems and fight against extreme disasters, a novel planning‐attack‐reconfiguration optimization method is proposed in this paper. Firstly, according to the processes of prevention, defence, and restoration for a resilient distribution system through disruption, the novel resilience evaluation indicators are presented, which include the node degree of distributed generation (DG) bus, survival rate, and recovery ability. Secondly, a novel planning‐attack‐reconfiguration optimization model is developed to improve the resilience of distribution systems. In DG planning stage, the multi‐objective planning model is formulated, which includes the minimization of the total cost of investment and operation, and the maximization of the node degree of DG buses for critical loads. In the attack stage, a clear worst case of N‐k contingencies on the basis of generalized nodes is presented to reduce the computational complexity. Then, the post‐disaster network reconfiguration model is formulated to maximize the restoration rate of critical loads (RRCL). Finally, the proposed method is illustrated by the case study on PG&E 69‐bus distribution system. The simulation results indicate that all the RRCL can reach about 90% in the four multipoint fault scenarios. Meanwhile, other evaluation indicators are greatly improved. It is shown that the resilience of distribution systems can be dramatically enhanced by the proposed method.
