“…The research on the resilience of power systems mainly focuses on two aspects. In Ma et al, 18 a two-stage stochastic mixed-integer programming framework to protect distribution systems against extreme natural disasters is proposed, considering the allocations of DG and automatic switches. [10][11][12][13] The other are the methods and measures to enhance the resilience of power systems, mainly focusing on the three stages of the function curve, which include the prevention, defence, and restoration.…”

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.

“…Salman et al (2015) proposed a framework considering failure of poles and power delivery, component importance measure, hurricane hazard analysis, and decay of poles to evaluate the effectiveness of targeted hardening strategies on power distribution systems subjected to hurricanes. Ma et al (2017) derived an optimal hardening strategy for distribution networks by proposing a tri-level optimization model that considers the probabilistic failures of hardened components to protect the grid against extreme weather events.…”

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.

“…Loss of Load Expectation (LOLE) and Loss of Load Frequency (LOLF) were used as indices in [24][25][26]. The other indices that are also commonly used to express grid resilience are Expected Energy Not Supplied (EENS) [27,28] and the amount of load shedding [29,30]. These indices measure grid resilience in terms of the impact.…”

Concerns about the power outages caused by extreme weather events have led the study of grid resilience. Among the grid resilience studies, this paper presents an overview to evaluate and improve grid resilience through the analysis of determinants of the impact and the grid capability. The impact is determined by the extreme weather events, grid exposure, and grid vulnerability. Whereas, the determinants of the grid capability are physical durability, operational versatility, and rehabilitation capacity. Conceptual knowledge for quantifying the impact and the grid capability is also presented. Then, some improvement strategies to reduce the impact and to improve the grid capability based on their determinants are discussed. The study of the impact and the grid capability provides a preliminary guideline to plan appropriate grid resilience improvement strategies.
