Graph Machine Learning: An Opportunity for Power Systems
Martin Sadric, Sebastian Pütz, Christian Nauck +4
Modern power systems face growing operational complexity driven by the integration of renewable energy sources, decentralization, and the need for real-time decision-making across…
A graph theoretic view on small signal stability of inverter-based power grids
Iva Bačić, Jakob Niehues, Philipp C. Böttcher +5
Dynamic grid stability is traditionally ensured with synchronous generators. Modern grids rely substantially more on inverter-based resources, which require grid-forming control to…
Transmission Topology Optimization using accelerated MapElites
Nico Westerbeck, Leonard Hilfrich, Dirk Witthaut
Transmission Topology Optimization has great potential to improve efficiency and flexibility of grid operations through non-costly switching actions, but previous approaches strugg…
Cascading Failures and Critical Infrastructures in Future Renewable European Power Systems
Maurizio Titz, Franz Kaiser, Johannes Kruse +8
The world's power systems are undergoing a rapid transformation, shifting away from carbon-intensive power generation to renewable sources. As a result, electricity is being transp…
Impact of Market Reforms on Deterministic Frequency Deviations in the European Power Grid
Philipp C. Böttcher, Carsten Hartmann, Andrea Benigni +2
Deterministic frequency deviations (DFDs) are systematic and predictable excursions of grid frequency that arise from synchronized generation ramps induced by electricity market sc…
Towards Quantum Algorithms for the Optimization of Spanning Trees: The Power Distribution Grids Use Case
Carsten Hartmann, Nil Rodellas-Gràcia, Christian Wallisch +5
Optimizing the topology of networks is an important challenge across engineering disciplines. In energy systems, network reconfiguration can substantially reduce losses and costs a…
Cyber-Physical Systems on the Megawatt Scale: The impact of battery control on grid frequency stability
Carsten Hartmann, Edoardo De Din, Daniele Carta +9
Electric power systems are undergoing fundamental change. The shift to inverter-based generation challenges frequency stability, while growing digitalisation heightens vulnerabilit…
Phase locking and multistability in the topological Kuramoto model on cell complexes
Iva Bačić, Michael T. Schaub, Jürgen Kurths +1
Higher-order interactions fundamentally shape collective dynamics in oscillator networks. The topological Kuramoto model captures these effects by extending synchronization models…
Voltage-sensitive distribution factors for contingency analysis and topology optimization
Maurizio Titz, Dirk Witthaut, Joost van Dijk +2
Topology optimization is a promising approach for mitigating congestion and managing changing grid conditions, but it is computationally challenging and requires approximations. Co…
Symmetry breaking in minimum dissipation networks
Aarathi Parameswaran, Andrea Benigni, Dirk Witthaut +1
Both natural and engineered supply networks exhibit universal structural patterns, such as the formation of loops, yet the principles governing optimal structures remain unclear. T…
