Did 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.

This would require both grids to be exactly synchronized.

It's possible to transfer power between two grids at different frequencies (even between 50 and 60 Hz), it just requires more expensive equipment.

I like the site. Unfortunately for this American, having a different set of standards for mathematical notation tripped a "don't these people know the difference between Hz and kHz?" impulse in my brain. To illustrate: When an American sees "50,000 Hz" we process it as you would process "50 000 Hz". This misunderstanding could be corrected by using two or four significant figures after the decimal. That's too much to…

AFAIK it's entirely possible to adjust it based on the browser's locale

There's by now a lot of DC links in Europe for example going from the European continental grid to the Nordic grid. Denmark is split between the two so it has a country internal DC link too.

On 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 infra…

For other folks who find grid identity as a shared frequency fascinating, this week's Complex Systems podcast won't disappoint.

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

Whoever chose it must have been aware of the use of 60 in time measurement and its practicality: 60 min/hr, 60 sec/min, 60 cycles/sec.

Time traveling Babylonians are proud to have 60Hz electricity.
