Not grid following inverters, or "any DC source", as we saw in Spain in Summer

Nothing to do with the blackout in Spain - https://www.reuters.com/business/energy/what-caused-iberian-... - voltage surge and various thermal power generators failing to provide the voltage correction services they were being paid for

But yes, grid following alone does not provided the required stability - synthetic inertia etc needed

Yes, if you don't install grid stabilization inverters, they don't supply grid stabilization.

From what I saw: In Spain, inverters are not allowed to provide voltage control, and what we saw in Spain, was a voltage spike that caused generators to drop offline, which then caused frequency issues.

		See report and first comment: https://news.ycombinator.com/item?id=44358668 It looked to me that regulators wanted to make solar the scapegoat for political reasons. The report indicates to me that different operators were using a random monkey theory to make changes until the grid stabilised (they clearly didn't have a handle on the root cause of the instabilities). The regulator screwed up: they are supposed to engineer the network so it can be stable (even in the face of political pressure).
