We use the OPA complex systems model of the power transmission system to investigate the effect of a series of different network upgrade scenarios on the long time dynamics and the probability of...
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...

Non-diffusive transport in plasma turbulence: a fractional diffusion approach (2004)
Numerical evidence of non-diffusive transport in three-dimensional, resistive pressure-gradient-driven plasma turbulence is presented. It is shown that the probability density function (pdf) of test...

Dynamics, Criticality and Self-organization in a Model for Blackouts (2002)
B. A. Carreras, I. Dobson, V. E. Lynch, D. E. Newman
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...
