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…
Accelerated DC loadflow solver for topology optimization
Nico Westerbeck, Joost van Dijk, Jan Viebahn +2
We present a massively parallel solver that accelerates DC loadflow computations for power grid topology optimization tasks. Our approach leverages low-rank updates of the Power Tr…
