Parameter Optimisation of a Virtual Synchronous Machine in a Microgrid
Timo Dewenter, Wiebke Heins, Benjamin Werther +3
Parameters of a virtual synchronous machine in a small microgrid are optimised. The dynamical behaviour of the system is simulated after a perturbation, where the system needs to r…
Convex Hulls of Multiple Random Walks: A Large-Deviation Study
Timo Dewenter, Gunnar Claussen, Alexander K. Hartmann +1
We study the polygons governing the convex hull of a point set created by the steps of independent two-dimensional random walkers. Each such walk consists of discrete time…
Large-deviation properties of resilience of power grids
Timo Dewenter, Alexander K. Hartmann
We study the distributions of the resilience of power flow models against transmission line failures via a so-called backup capacity. We consider three ensembles of random networks…
Exact ground states of one-dimensional long-range random-field Ising magnets
Timo Dewenter, Alexander K. Hartmann
We investigate the one-dimensional long-range random-field Ising magnet with Gaussian distribution of the random fields. In this model, a ferromagnetic bond between two spins is pl…
Phase transition for cutting-plane approach to vertex-cover problem
Timo Dewenter, Alexander K. Hartmann
We study the vertex-cover problem which is an NP-hard optimization problem and a prototypical model exhibiting phase transitions on random graphs, e.g., Erdoes-Renyi (ER) random gr…
