 You can find the details in the reports someone here posted earlier:
 https://www.neso.energy/document/152346/download
(figures 7 an 8 on page 20 are classic, they belong in a book on control
theory as an example of conditional stability)
 and the addendum:

These are for Britain's problem.  The thread, here, is about the fiasco
in Spain.
"Aagesen also blamed private generators for failing to regulate the grid's
voltage ..."
WHICH firms?  ALL of them??
"...and there were plants that were disconnected ‘improperly’, according
to Aagesen"
Again, which plants?  Was there policy in place that caused this (if so,
why hadn't ALL plants?)
"...because ‘some operators’ were not complying with the regulations"
Which?
"The report, due to a ‘confidentiality obligation’ has “anonymised”
information, ‘on most occasions’ at the request of the actors involved..."
Do you see the pattern, here?
I.e., "Someone was killed.  We've spoken to the killer -- who shall remain
anonymous and promise not to do it again..."

The wind farm failure was probably due to gradually adding more turbines,
thus increasing the open loop gain of reactive power control (which is
proportional to the number of generators in parallel) without readjusting
the controller gain set by the factory, probably based on the number of
turbines in the first batch ordered.  Do we blame the factory, the
operators, or the university professors who trained them?  Or just accept
that humans are not all knowing, learn something and move on.  The
simultaneous fossil fuel plant failure was also due to causes not
attributable to negligence im my interpretation of the report.
