What's with the title? Shouldn't it be singular instead of single?

The protections side is a big problem - most HVDC has circuit breakers operating on the HVAC sides of the link so going to full DC transmission presumably wouldn't eliminate that equipment.

Virtually all HVDC transmission currently operating is point to point mostly for control reasons. My understanding is it's very difficult to coordinate multiple converter stations - power flow in DC networks is fully determined by the control systems of the converters unlike AC networks which in general lack active control devices (see the FACTS family of devices for examples that can be used in AC networks to actively control power flow).
