Aagesen singled out the role of the Spanish grid operator REE and certain energy companies she did not name which disconnected their plants “inappropriately… to protect their installations.”
She also pointed to “insufficient voltage control capacity” on the system that day, due in part to a programming flaw, stressing that Spain’s grid is theoretically robust enough to handle such situations.
Due to these misjudgments “we reached a point of no return with an uncontrollable chain reaction” that could only have been managed if steps had been taken beforehand to absorb the overvoltage problems, she added.
Ah yes, solar power, known for causing programming flaws
Yeah right. All the solar cells just hacking into the repo, manupulating stuff
Considering just recently a bunch of chinese PV converters have been found to contain extra parts not in the schematics and can be made to create overvoltage remotely, without leaving evidence, I wouldn’t dismiss the possibility outright.
I mean, it wouldn’t have caused the failed voltage regulation itself, but it is realistically possible the initial cause of overvoltage was a hack.
Hard to rule out any possibility if we are just guessing and not requiring proof.
No, the overvoltage. The grid did not manage to handle the issue due to a programming flaw.
