Correct me if i'm wrong, it's been a while since i watched this grid engineer's explanation, 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 turbine outputs with HVDC feed for example.

where i think the story gets further 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".

imo the distinction is important, it's not a PROBLEM with PV, it's a problem with previous assumptions about renewables capacity & grid state no longer being true, and the ways bureaucracies & their infrastructure decisions can lag behind that change.
