Inverters are the problem. They're closed source and power engineers cant test their fault behavior well.

(One of ) the problem with inverter the angular velocity of a spinning rotor is trivially easy to define and measure. The operating frequency of the grid that an inverter needs to target is hard to define under the realtime constraints of a failing grid.

Which is what brought Spain down. It wasnt the panels and windmills, it was the inverters.

It would, indeed, make sense to have standardised behaviour for the inverters (they can simulate inertia perfectly well, but a lot do not), and incentives to contribute that value to the grid. It's not a hard to define target if you just want something that looks like inertia.

And the root cause of the blackout in Spain is still mostly the subject of speculation. AFAIK there has is no official report yet into the details of how things went wrong.
