The hardware may be old, but the control strategy is new.

Most regulating entities have updated their modus operandi after
the big blackouts we have seen in the last couple of years.

In particular, most places the frequency tolerance have
been increased, both in frequency and duration.

Active research in this area is for the net to fall apart
into self-sustaining 'cells' but nobody has even dared
suggest a live test of this concept yet.

But since nobody has any better ideas, they keep trying
to make it look plausible somehow.

The major trouble in this area is that they never get to
run a live test so nobody knows what works until it 
(usually) is too late.

Never attribute to malice what can adequately be explained by incompetence.
