I read through solar radiation there was an event like “athmospheric oscillation”. But what exactly happend by that that caused the blackout?

If they give some vague reasons and suddenly everyone stops talking about it.
It means they know who or what really did it and they don’t want the public to know for reasons
There is no official answer yet and there have been multiple investigations announced.
There are two things ruled out:
What currently looks to have happened is that the grid lost a sudden 40% of the energy capacity in Northern Spain, immediately overloading the rest of the entire grid encompassing Spain, Portugal, Andorra and Southern France.
We don’t know yet. Proper investigation takes time and don’t go as fast as the newspaper.
The only real answer is that we don’t know yet.
Atmospheric oscillation was not confirmed by any real authority (and is not a real explanation by itself IMO).
Other than ruling out a cyber attack the precise source of the blackout has yet to be proved, what we have so far is speculation.
It’s still unclear. Known facts are that there was a significant amount of electricity coming from solar power and that there was a rather big dip in solar production in the south west of Spain (could simply have been from a cloud coming in from the sea). Local backup production couldn’t increase production fast enough and the limited connections with the rest of Europe were not enough to compensate. This is one of those cases where a single domino simply causes a cascade and before you know it, you’re in the dark.
The sun can cause this kind of thing: https://en.wikipedia.org/wiki/March_1989_geomagnetic_storm
Not saying that’s what’s happened here…
Nobody knows “yet”.
Maybe this is what those AI CEO’s tried warning us about? 👀
We don’t know. One possible cause is a cascade failure, like what happened in Canada and the US in 2004(?). There are several factors involved, but essentially, one line sagged due to excessive load, hit a tree, shorted out, tripped breakers and the load had to be picked up by other lines. Those lines in turn became overloaded and tripped, each time making the situation worse, until the whole network failed.
Imagine you’re juggling slightly too many hammers, and you stub your finger on one, breaking it. You now have to juggle the same number of hammers with an injured hand, which causes you to slip and keep breaking fingers until you drop all the hammers at once.
As others have said a full explanation has not been produced.
I did see mention of a problem with one of the French-Spanish interconnects, with the comment that this in itself wouldn’t be enough to explain the issue. So could well be more than one thing happened at the same time.
Just read an article that contrast the ability of large spinning generators to handle fluctuations in a manner that solar and wind can’t. There have been articles on the problems renewables have to rapidly adjusting needs.
The gist of the article was Spain’s reliance on renewables could have been the culprit.
Now we enter the realm of politics and will never know the reason.
