Synchronized states of power grids and oscillator networks by convex optimization
Carsten Hartmann, Philipp C. Böttcher, David Gross +1
Synchronization is essential for the operation of AC power systems: All generators in the power grid must rotate with fixed relative phases to enable a steady flow of electric powe…
Identifying drivers and mitigators for congestion and redispatch in the German electric power system with explainable AI
Maurizio Titz, Sebastian Pütz, Dirk Witthaut
The transition to a sustainable energy supply challenges the operation of electric power systems in manifold ways. Transmission grid loads increase as wind and solar power are ofte…
Regulatory Changes in Power Systems Explored with Explainable Artificial Intelligence
Sebatian Pütz, Johannes Kruse, Dirk Witthaut +2
A stable supply of electrical energy is essential for the functioning of our society. Therefore, the electrical power grid's operation and energy and balancing markets are subject…
Stability bounds of droop-controlled inverters in power grid networks
Philipp C. Böttcher, Leonardo Rydin Gorjão, Dirk Witthaut
The energy mix of future power systems will include high shares of wind power and solar PV. These generation facilities are generally connected via power-electronic inverters. Whil…
Physics-inspired machine learning for power grid frequency modelling
Johannes Kruse, Eike Cramer, Benjamin Schäfer +1
The operation of power systems is affected by diverse technical, economic and social factors. Social behaviour determines load patterns, electricity markets regulate the generation…
Predicting Dynamic Stability from Static Features in Power Grid Models using Machine Learning
Maurizio Titz, Franz Kaiser, Johannes Kruse +1
A reliable supply with electric power is vital for our society. Transmission line failures are among the biggest threats for power grid stability as they may lead to a splitting of…
Understanding Braess' Paradox in power grids
Benjamin Schäfer, Thiemo Pesch, Debsankha Manik +5
The ongoing energy transition requires power grid extensions to connect renewable generators to consumers and to transfer power among distant areas. The process of grid extension r…
Revealing interactions between HVDC cross-area flows and frequency stability with explainable AI
Sebastian Pütz, Benjamin Schäfer, Dirk Witthaut +1
The energy transition introduces more volatile energy sources into the power grids. In this context, power transfer between different synchronous areas through High Voltage Direct…
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…
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…
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…
From State Estimation to Network Reconstruction
Farnaz Basiri, Jose Casadiego, Marc Timme +1
We develop methods to efficiently reconstruct the topology and line parameters of a power grid from the measurement of nodal variables. We propose two compressed sensing algorithms…
A Dual Method for Computing Power Transfer Distribution Factors
Henrik Ronellenfitsch, Marc Timme, Dirk Witthaut
Power Transfer Distribution Factors (PTDFs) play a crucial role in power grid security analysis, planning, and redispatch. Fast calculation of the PTDFs is therefore of great impor…
