Re: Baltic countries disconnect from the Russian power grid
#2On Saturday (8th of Feb), Baltic countries will disconnect from the Russian power grid and synchronise with the Continental European electricity system. They will operate in "island mode" for 33 hours, and then synchronize with the European grid frequency.
The frequency is a key parameter of the grid. If there is too much load, it goes down, and if there is too much production it goes up. A lot of critical grid infrastructure relies on the frequency being in the 49.5-50.5 Hz range.
I built a tool together with some colleagues to track the grid frequency in real time during this operation over the past few days to follow this process in real time!
If you're curious for more details, there is also a great post on the Estonian TSO's website about the process: https://elering.ee/en/synchronization-continental-europe

#3This is very interesting, and the web-site is very nicely done.

#4Did they consider connecting to both grids at the same time making a bigger 'supergrid'?
If there is insufficient connectivity between the grids and the connections all disconnect due to overload, you just end up back in the two-grids situation that they have planned anyway.

Off-topic;
Why does America use 60Hz? I've never found a satisfactory answer.

This would require both grids to be exactly synchronized.

These frequencies are often inherited from whoever was the first grid operator, and electricity producer. Same goes for lot of other parameters.

#9What does it actually mean to disconnect? Is there some physical connection being broken? How is that done?

#10Gosh I love these electricity grid posts. As someone with almost zero knowledge about the subject, I am fascinated by what I learn. The last one I saw was when Ukraine switched away from Russia days before Russia invaded them.
