Large-deviation properties of oscillator models of energy grids — •Yannick Feld and Alexander K. Hartmann — Institute of Physics, University of Oldenburg, Germany

The exit from nuclear and fossil-fuel energy is resulting in the need for extensive installation of renewable energy generators. Therefore maintaining a stable energy grid becomes more challenging. To find very stable and very unstable grid topologies we apply Markov Chain Monte Carlo simulations of random networks. With large-deviation techniques, specifically by using an artifical finite-temperature (Boltzmann) ensemble, one can access a broad range of the network probability distribution up to very small probability densities (e.g. 10⁻⁵⁰)[1]. In the past large-deviation properties of static power grids were investigated [2]. Here we apply the same approach to a dynamic model of power grids, specifically a Kuramoto-like model [3].
