Comment on they know what they need to do

This lack of inertia due to few more traditional energy sources had been identified previously and the Portuguese national grid had plans to install artificial ballasts of sorts to create that inertia (plans which were delayed multiple times iirc)

Ah gotcha, yeh afaik that was definitely a grid failure rather than renewables failure in any form.

It was a grid failure triggered by a poor management of one of the problems of solar, which is NOT being produced with turbines

Correct me if i’m wrong, it’s been a while since i watched this grid engineer’s video), but my understanding was it has nothing to do with PV itself, it began with IBR misconfiguration which under “unusual circumstances” cascaded due to further grid mismanagement.
yes the misconfigured IBR were at a PV plant, but thats where i think the media runs with the story without really communicating clearly to the public. IBR misconfiguration, even at a PV plant, is not a technical failure of PV technology itself, at all. IBR misconfiguration also effects turbines with HVDC feed for example.
where i think the story also gets jumbled is alot of the “unusual circumstances” involved issues which were traceable (under current implementations) to a renewables dominant grid state. so the news story seems to become “PV/renewables trouble”, whereas afaict in reality it’s more like “renewables dominating to unexpected levels + misconfiguration/mismanagement”. and let’s face it, the era of renewables dominant grid states is only just beginning, this is new territory.
imo the distinction is important, it’s not a PROBLEM with PV, it’s a problem with previous assumptions about renewables capacity no longer being true, and the ways bureaucracies can lag behind that change.
