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…
Approximability of Electrical Distribution Network Reconfiguration for General Graphs
Christian Wallisch, Andrea Benigni, Carsten Hartmann +1
Electrical distribution networks are regional, medium- and low-voltage power grids connecting energy sources to individual households and businesses with given power demands. While…
CHAMB-GA: A Containerized HPC Scalable Microservice-Based Framework for Genetic Algorithms
Felix Bonhoff, Thiemo Pesch, Andrea Benigni +2
Metaheuristic-based global optimization with embedded, long-running simulations is a computationally expensive process. To support various stages of development and execution, a se…
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…
Quantum search algorithm for similar subgraph identification under fixed edge removal
Ruben Kara, Sven Danz, Tobias Stollenwerk +1
We introduce a novel quantum algorithm for similar subgraph identification in form of an NP-hard cardinality-constrained binary quadratic optimization problem. Given a weighted ref…
Quantum Technologies and Edge Devices in Electrical Grids: Opportunities, Challenges, and Future Directions
Marjorie Hoegen, René Glebke, M. Sahnawaz Alam +11
In modern power systems, edge devices serve as local hubs that collect data, perform on-site computing, sense electrical parameters, execute control actions, and communicate with n…
