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…
Small-signal stability of power systems with voltage droop
Jakob Niehues, Robin Delabays, Anna Büttner +1
The stability of inverter-dominated power grids remains an active area of research. This paper presents novel sufficient conditions for ensuring small-signal stability in lossless…
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…
Complex Phase Analysis of Power Grid Dynamics
Jakob Niehues, Anna Büttner, Anne Riegler +1
With an increasing share of renewable energy sources, accurate and efficient modeling of grid-forming inverters is becoming crucial for system stability. Linear methods are a power…
Probabilistic Behavioral Aggregation: A Case Study on the Nordic Power Grid
Anna Büttner, Frank Hellmann
This study applies the Probabilistic Behavioral Tuning (ProBeTune) framework to transient power grid simulations to address challenges posed by increasing grid complexity. ProBeTun…
