Validation Methods for Energy Time Series Scenarios from Deep Generative Models
Eike Cramer, Leonardo Rydin Gorjão, Alexander Mitsos +3
The design and operation of modern energy systems are heavily influenced by time-dependent and uncertain parameters, e.g., renewable electricity generation, load-demand, and electr…
Secondary control activation analysed and predicted with explainable AI
Johannes Kruse, Benjamin Schäfer, Dirk Witthaut
The transition to a renewable energy system poses challenges for power grid operation and stability. Secondary control is key in restoring the power system to its reference followi…
Secondary frequency control stabilizing voltage dynamics
Eder Batista Tchawou Tchuisseu, Eric-Donald Ndogmo, Pavel Procházka +3
The ongoing energy transition challenges the stability of the electrical power system. Stable operation of the electrical power grid requires both the voltage (amplitude) and the f…
Fluctuations of water quality time series in rivers follow superstatistics
Benjamin Schäfer, Catherine M. Heppell, Hefin Rhys +1
Superstatistics is a general method from nonequilibrium statistical physics which has been applied to a variety of complex systems, ranging from hydrodynamic turbulence to traffic…
Exploring deterministic frequency deviations with explainable AI
Johannes Kruse, Benjamin Schäfer, Dirk Witthaut
Deterministic frequency deviations (DFDs) critically affect power grid frequency quality and power system stability. A better understanding of these events is urgently needed as fr…
Revealing drivers and risks for power grid frequency stability with explainable AI
Johannes Kruse, Benjamin Schäfer, Dirk Witthaut
Stable operation of the electrical power system requires the power grid frequency to stay within strict operational limits. With millions of consumers and thousands of generators c…
Phase and amplitude synchronisation in power-grid frequency fluctuations in the Nordic Grid
Leonardo Rydin Gorjão, Luigi Vanfretti, Dirk Witthaut +2
Monitoring and modelling the power grid frequency is key to ensuring stability in the electrical power system. Many tools exist to investigate the detailed deterministic dynamics a…
Spatio-temporal complexity of power-grid frequency fluctuations
Leonardo Rydin Gorjão, Benjamin Schäfer, Dirk Witthaut +1
Power-grid systems constitute one of the most complex man-made spatially extended structures. These operate with strict operational bounds to ensure synchrony across the grid. This…
How Decentral Smart Grid Control limits non-Gaussian power grid frequency fluctuations
Benjamin Schäfer, Dirk Witthaut, Marc Timme
Frequency fluctuations in power grids, caused by unpredictable renewable energy sources, consumer behavior and trading, need to be balanced to ensure stable grid operation. Standar…
Isolating the impact of trading on grid frequency fluctuations
Benjamin Schäfer, Marc Timme, Dirk Witthaut
To ensure reliable operation of power grids, their frequency shall stay within strict bounds. Multiple sources of disturbances cause fluctuations of the grid frequency, ranging fro…
Statistical Characterization of Airplane Delays
Evangelos Mitsokapas, Benjamin Schäfer, Rosemary J. Harris +1
The aviation industry is of great importance for a globally connected economy. Customer satisfaction with airlines and airport performance is considerably influenced by how much fl…
