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…
Towards Quantum Algorithms for the Optimization of Spanning Trees: The Power Distribution Grids Use Case
Carsten Hartmann, Nil Rodellas-Grà cia, 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…
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…
