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…
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-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…
Quantum Annealing based Power Grid Partitioning for Parallel Simulation
Carsten Hartmann, Junjie Zhang, Carlos D. Gonzalez Calaza +3
Graph partitioning has many applications in powersystems from decentralized state estimation to parallel simulation. Focusing on parallel simulation, optimal grid partitioning mini…
