Domain-independent detection of known anomalies

1 code implementation3 Jul 2024 Jonas Bühler, Jonas Fehrenbach, Lucas Steinmann, Christian Nauck, Marios Koulakis

In real-world use cases, two problems must be addressed: anomalous data is sparse and the same types of anomalies need to be detected on previously unseen objects.

Predicting Fault-Ride-Through Probability of Inverter-Dominated Power Grids using Machine Learning

1 code implementation13 Jun 2024 Christian Nauck, Anna Büttner, Sebastian Liemann, Frank Hellmann, Michael Lindner

Importantly, we demonstrate that ML models accurately predict the fault-ride-through probability of synthetic power grids.

Predicting Instability in Complex Oscillator Networks: Limitations and Potentials of Network Measures and Machine Learning

1 code implementation27 Feb 2024 Christian Nauck, Michael Lindner, Nora Molkenthin, Jürgen Kurths, Eckehard Schöll, Jörg Raisch, Frank Hellmann

A functional property that is of theoretical and practical interest for oscillatory systems is the stability of synchrony to localized perturbations.

Toward Dynamic Stability Assessment of Power Grid Topologies using Graph Neural Networks

1 code implementation10 Jun 2022 Christian Nauck, Michael Lindner, Konstantin Schürholt, Frank Hellmann

As a testbed for GNN models, we generate new, large datasets of dynamic stability of synthetic power grids, and provide them as an open-source resource to the research community.

Predicting Basin Stability of Power Grids using Graph Neural Networks

1 code implementation18 Aug 2021 Christian Nauck, Michael Lindner, Konstantin Schürholt, Haoming Zhang, Paul Schultz, Jürgen Kurths, Ingrid Isenhardt, Frank Hellmann

We investigate the feasibility of applying graph neural networks (GNN) to predict dynamic stability of synchronisation in complex power grids using the single-node basin stability (SNBS) as a measure.
