1 TH/P2-17 Pulse propagation in a simple probabilistic transport model (2008)
B. A. Carreras, V. E. Lynch, R. Sánchez
Abstract. The response to perturbations of a simplified transport model is studied. The model is used as a paradigmatic example of transport controlled by a critical gradient. Long-time system...

A loading-dependent model of probabilistic cascading failure (2005)
Ian Dobson, Benjamin A. Carreras, David E. Newman, I. Dobson, B. A. Carreras, D. E. Newman
We propose an analytically tractable model of loading-dependent cascading failure that captures some of the salient features of large blackouts of electric power transmission systems+ This leads to a...
Blackout mitigation assessment in power transmission systems (2003)
Electric power transmission systems are a key infrastructure and blackouts of these systems have major direct and indirect consequences on the economy and national security. Analysis of North...

Growth and propagation of disturbances in a communication network model (2002)
In a society in which information is one of the highest-valued commodities, information networks are the economic backbone. Therefore, network vulnerability is a major hazard. Analysis of...
Dynamics, Criticality and Self-organization in a Model for Blackouts (2002)
A model has been developed to study the global complex dynamics of a series of blackouts in power transmission systems [1, 2]. This model has included a simple level of self-organization by...

Modeling Blackout Dynamics, B. A. Carreras, I. Dobson
A model for blackouts in electric power transmission systems is implemented and studied in simple networks with a regular structure. The model describes load demand and network improvements evolving...
Initial evidence for self-organized criticality in electric power blackouts (2000)
We examine correlations in a time series of electric power system blackout sizes using scaled window variance analysis and R/S statistics. The data shows some evidence of long time correlations and...
Initial evidence for self-organized criticality in electric power blackouts (2000)
We analyze a 15-year time series of North American electric power system blackouts for evidence of selforganized criticality. Scaled window variance and R/S analysis of the time series shows moderate...
