Gemessen mit einem Oszilloskop über 48 Stunden, mit einer Abtastrate von 1 Hz.
Das zweite Bild ist eine Fourier-Analyse des Frequenzzeitreihen, das heißt, es zeigt die Frequenzfrequenzen. Die DC-Vorspannung (50 Hz) wurde ebenfalls abgezogen.

Very interesting that you can see that power is now mainly traded in 15-minute invervals in the day-ahead market: [https://energy.ec.europa.eu/news/eu-electricity-trading-day-ahead-markets-becomes-more-dynamic-2025-10-01_en](https://energy.ec.europa.eu/news/eu-electricity-trading-day-ahead-markets-becomes-more-dynamic-2025-10-01_en)
How did you measure a frequency of 50Hz with a sampling rate of 1Hz? Souldn’t you use at least 100Hz for that?
Edit: i’m dumb. i guess your sampling rate was much higher, but you saved one value every second.
You should actually be able to corellate the frequency with the price changes.
When there’s slightly less power than what was agreed, the frequency goes down a bit and vice versa.
There’s a special set of trading rules surrounding who is chosen to supply the excess.
