Identifying critical infrastructures in complex supply networks — •Dirk Witthaut — Institut für Energie- und Klimaforschung, Forschungszentrum Jülich — Institut für theoretische Physik, Universität zu Köln — Max-Planck-Institut für Dynamik und Selbstorganisation

Transmission line failures can induce large-scale outages in power grids and other complex supply networks, causing potentially huge economic losses. Yet, how to determine which lines are particularly sensitive to inducing larger-scale outages is currently not well understood. In this talk I will discuss how the topological redundancy of a transmission line limits dynamical network robustness and allows to reliably identify critical infrastructures. I derive criteria to predict the dynamic stability of power grids based on the networks topology and the static loads prior to line failure. As both criteria are available before any outage from the state of normal operation, they may support network planning and real-time monitoring of grid operation.
