Study on Interaction Process Between Virus Propagation and Cascading Failure [PDF]
Jisuanji gongcheng, 2017 In order to study the influence of clustering coefficient on interaction of virus propagation and cascading failure,an improved interaction model of virus propagation and cascading failure is proposed.Network clustering coefficients are adjusted by ...

Research on Cascading Failure Model of Urban Regional Traffic Network under Random Attacks
Discrete Dynamics in Nature and Society, 2018 For better describing the network cascading failure caused by random attacks such as traffic accidents, this paper introduces the ORNL-PSerc-Alaska (OPA) model to analyze the urban regional traffic network vulnerability. Firstly, the double-layer network

Cyber Attacks on Power Grids: Causes and Propagation of Cascading Failures
IEEE Access, 2023 Cascading effects in the power grid involve an uncontrolled, successive failure of elements. The root cause of such failures is the combined occurrence of multiple, statistically rare events that may result in a blackout.

Cascading failures in ac electricity grids [PDF]
Physical Review E, 2016 Sudden failure of a single transmission element in a power grid can induce a domino effect of cascading failures, which can lead to the isolation of a large number of consumers or even to the failure of the entire grid. Here we present results of the simulation of cascading failures in power grids, using an alternating current (AC) model.

Preventing cascading failure of electric power protection systems in nuclear power plant
Nuclear Engineering and Technology, 2021 Cascading failure is the main cause of large blackouts in electrical power systems; this paper analyzes a cascading failure in Hanbit nuclear power plant unit two (2) caused by a circuit breaker (CB) operation failure.

AN URN MODEL FOR CASCADING FAILURES ON A LATTICE [PDF]
Probability in the Engineering and Informational Sciences, 2012 A cascading failure is a failure in a system of interconnected parts, in which the breakdown of one element can lead to the subsequent collapse of the others. The aim of this paper is to introduce a simple combinatorial model for the study of cascading failures.

Model for cascading failures in complex networks [PDF]
Physical Review E, 2004 Large but rare cascades triggered by small initial shocks are present in most of the infrastructure networks. Here we present a simple model for cascading failures based on the dynamical redistribution of the flow on the network. We show that the breakdown of a single node is sufficient to collapse the efficiency of the entire system if the node is ...

Cascading Failures in Power Grids
CoRR, 2022 This paper studies the consequences of a human-initiated targeted attack on the national electric power system. We consider two kinds of attacks: ($i$) an attack by an adversary that uses a tactical weapon and destroys a large part of the grid, by physically targeting a large geographic region; ($ii$) a targeted attack by an adversary that takes out a ...
