The redistribution of power flow in cascading failures

2013 51st Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2013
Understanding the redistribution of power flow is crucial to understanding the dynamics of cascading failures. Such redistribution is complicated, with monotonicity being the exception rather than the norm. We study the monotonicity of a quadratic function of branch power flow with respect to link failure and load shedding, respectively.

Catastrophic cascade of failures in interdependent hypergraphs

Chaos: An Interdisciplinary Journal of Nonlinear Science
The failures of individual agents can significantly impact the functionality of associated groups in interconnected systems. To reveal these impacts, we develop a threshold model to investigate cascading failures in double-layer hypergraphs with interlayer interdependence.

Analysis of cascading failures

2016
Inspired by analyzing the reliability of energy networks, particularly the occurrence of large blackouts, we consider a stylized model of cascading failures. By using connections with extreme value theory and Brownian bridge approximations, we establish that the number of failed nodes follow a power law.

The Research on Cascading Failure of Farey Network

2017
Cascading failure is an important part of the dynamics in complex network. In this paper, we research the cascading failure of Farey network which is scale-free network with fractal properties by data analysis. According to the analyses, we obtain an iterative expression of the failure nodes’ number at the certain time step, anther iterative expression
