A graph theoretic view on small signal stability of inverter-based power grids
Iva BaÄiÄ, 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…
Phase locking and multistability in the topological Kuramoto model on cell complexes
Iva BaÄiÄ, 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…
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…
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…
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…
