Data-driven analysis of the power grid frequency — •Benjamin Schäfer1, Christian Beck1, Leonardo Rydin Gorjão2,3, Johannes Kruse2,3, and Dirk Witthaut2,3 — 1School of Mathematical Sciences, Queen Mary University of London, London E1 4NS, United Kingdom — 2Forschungszentrum Jülich, Institute for Energy and Climate Research-Systems Analysis and Technology Evaluation (IEK-STE), Jülich, Germany — 3Institute for Theoretical Physics, University of Cologne, Köln, Germany
The Paris conference 2015 set a path to limit climate change to "well below 2°C". To reach this goal greenhouse gas emissions have to be reduced and renewable generators, electrical mobility or smart grids are integrated into the existing power system.
The introduction of these new technologies raises several questions about control, stability and operation and therefore requires a solid understanding of existing and future systems and new conceptional approaches.
Here, we use data-driven approaches to work towards a quantitative understanding of the power grid with a particular focus on the power grid frequency. We analyse time series from various synchronous areas such as Continental Europe, Great Britain but also two US areas and several European islands.
We highlight significant deviations from Gaussianity in several regions, scaling laws and spatio-temporal dynamics. Finally, we discuss how past information may be used to forecast the frequency.
