grid synchronization 'issues' are a feature, not a bug - by very, very slightly varying how hard to you try to 'push' out of synch you can manipulate power flows at will. This is dramatically more difficult with DC. That, and ease of voltage level manipulation were the reasons so much transmission was AC in the first place!
- XorNot 5y agoNo they're issues: if it was easy, then no one would bother with HVDC - HVDC exists because it reduces losses and vastly eases grid coordination because conversion to and from AC at either end is handled under local control and can be totally independent of the source/destination. Its the difference between just shifting the frequency or phase on your local control clock at the substation, and trying to coordinate with another state/territory/nation's entire AC generation infrastructure to keep everything in phase.
