Nodal Braess's Paradox and Inertia Destabilization with Dynamic Node and Line Failures in Power Grids
Nubius Brandner, Frank Hellmann, Hans Würfel +3
Large-scale power outages are typically caused by cascading failures. These unfold dynamically through complex interactions between network dynamics and individual component failur…
Distributed Adaptive Control for DC Power Distribution in Hybrid-Electric Aircraft: Design and Experimental Validation
Wasif H. Syed, Juan E. Machado, Hans Würfel +2
To reduce CO2 emissions and tackle increasing fuel costs, the aviation industry is swiftly moving towards the electrification of aircraft. From the viewpoint of systems and control…
Complex-Phase, Data-Driven Identification of Grid-Forming Inverter Dynamics
Anna Büttner, Hans Würfel, Sebastian Liemann +2
The increasing integration of renewable energy sources (RESs) into power systems requires the deployment of grid-forming inverters to ensure a stable operation. Accurate modeling o…
Consensus + Innovations Approach for Online Distributed Multi-Area Inertia Estimation
Nicolai Lorenz-Meyer, Hans Würfel, Johannes Schiffer
The reduction of overall system inertia in modern power systems due to the increasing deployment of distributed energy resources is generally recognized as a major issue for system…
