Nonlocal effects and countermeasures in cascading failures [PDF]

open access: yesPhysical Review E, 2015
We study the propagation of cascading failures in complex supply networks with a focus on nonlocal effects occurring far away from the initial failure. It is shown that a high clustering and a small average path length of a network generally suppress nonlocal overloads. These properties are typical for many real-world networks, often called small-world

Stochastic Models of Cascading Failures [PDF]

open access: yesJournal of Applied Probability, 2008
What is a ‘cascading failure’? Whilst most people have an intuitive idea of what is meant by cascading, no definition exists within the framework of reliability theory. The aim of this paper is to explore the field of component dependence within a network structure, and to construct a definition of cascading failure.

Analysis on Invulnerability of Wireless Sensor Network towards Cascading Failures Based on Coupled Map Lattice

open access: yesComplexity, 2018
Previous research of wireless sensor networks (WSNs) invulnerability mainly focuses on the static topology, while ignoring the cascading process of the network caused by the dynamic changes of load.

Modeling cascading failures and mitigation strategies in PMU based cyber-physical power systems

open access: yesJournal of Modern Power Systems and Clean Energy, 2018
This paper presents a model of cascading failures in cyber-physical power systems (CPPSs) based on an improved percolation theory, and then proposes failure mitigation strategies.

Bioinspired Mitigation Scheme for Cascading Failures in Farmland Wireless Sensor Networks

open access: yesComplexity, 2020
Existing mitigation strategies on wireless sensor networks (WSNs) against cascading failures cannot appropriately adapt the particular characteristics of farmland WSNs. Spider web provides a new reference for improving network invulnerability.

Frequent Pattern Growth-Based Identification of Critical Lines in Cascading Failures for Renewable-Dominant Hybrid AC/DC Power Systems

open access: yesEngineering
In wind and solar renewable-dominant hybrid alternating current/direct current (AC/DC) power systems, the active power of high-voltage direct current (HVDC) system is significantly limited by the security and stability events caused by cascading failures.

Cascading Dynamics of Heterogenous Scale-Free Networks with Recovery Mechanism

open access: yesAbstract and Applied Analysis, 2013
In network security, how to use efficient response methods against cascading failures of complex networks is very important. In this paper, concerned with the highest-load attack (HL) and random attack (RA) on one edge, we define five kinds of weighting ...

Estimation for Expected Energy Not Served of Power Systems Using the Screening Methodology of Cascading Outages in South Korea

open access: yesEnergies, 2017
The uncertainty of complex power systems increases the possibility of large blackouts due to the expectations of physical events, such as equipment failures, protection failures, control actions failure, operator error, and cyber-attacks.

Catastrophic cascade of failures in interdependent networks [PDF]

open access: yesNature, 2010
Many systems, ranging from engineering to medical to societal, can only be properly characterized by multiple interdependent networks whose normal functioning depends on one another. Failure of a fraction of nodes in one network may lead to a failure in another network. This in turn may cause further malfunction of additional nodes in the first network
