I wonder if life would be simpler if each generator had a local
controller and local control centre.

Probably needs still some external data flow for centralised
coordination/load balancing.
Could use non-duplicated  point-to-point links (no repeaters) with
encryption units at each end for these flows.

On the up-side:
Reduces risk of DOS and MITM attacks
Only lose 25% of generation if local controller fails

On the down-side
Design not redundant
- but could probably coordinate an unlinked generator manually if link
is lost
-  or order local centre to shut down the unlinked generator
More expensive
- manning, control systems
