What do you mean that "a number of distribution companies ... [are] older 
AC high-voltage transmission systems"?

IME, the distribution companies have specs that need to be met before one 
can interconnect.  What kind of optimization are you referring to?

All three interconnects are via DC.  However, within the ERCOT 
Interconnect, they use the same 60 cycle AC as everybody else.

But no generators interconnect with them!
