[time-nuts] Frequency jump in the European grid

[dschuecker]

On 05/30/2023 at 10:28:30 there was a remarkable frequency jump of 
+100mHz (m, not M ;)  ) within 10s  in the European ENTSO-E grid, see 
detail.png. Â  Within 1.5h things were back to normal, see full.png.


Reportedly

https://www.netzfrequenzmessung.de/aktuelles.htm#:~:text=Am%2030.05.2023%20um%2010,tempor%C3%A4r%20vom%20Verbundnetz%20abgekoppelt%20wurde.

Ukraine was split from ENTSO-E grid. The missing 1.4GW load cranked up 
the frequency. Allegedly frequency in Ukraine settled at only 48.2Hz. 
There is no information about the time of resync.

Before 2/24/22, the begin of the war, there where EU plans to disconnect 
UA from Russia and sync to ENTSO-E by 2023. These plans were speeded up 
and on 2/27/22 UA and Moldova asked for joining ENTSO-E, which took 
place on 3/16/22. So we had the bizarre situation that Europes' largest 
Nuclear Power Station Zaporizhia (5,7GW) produced energy for Europe 
under russian occupation. On 06/09/23 the last reactor was shut down.

Cheers
