But in the next-gen grids, AC might suck even more so we may still end up going down the DC route in the future.
Maybe for long, point to point links. Unlikely for regional and district scale distribution. The other problem with HVDC is it's hard to have multidrop, harder to add power in and even harder to have a drop that can either add or remove power.
Synchronus machines make that very easy on AC.
Wide scale grid synchronisation is very hard due to the speed of light, and AC is less efficient over ery long links, so distant, disparate grids are best linked with HVDC.
