... meanwhile, it's hard to believe that Japan still runs two separate grids at two separate frequencies. Seems like it'd be worth sorting out a transition plan instead of building that sort of facility, and (presumably) a bunch of others just like it.
- bee_rider 3y agoI think they might want HVDC either way, and since they’ll have to convert from DC to AC locally anyway, maybe it isn’t so bad? It does seem a little weird though.
- andylynch 3y agoIt’s not worth the eye watering amount of money it would cost to change. It took nearly seventy years to transition users off the much smaller NYC DC grid, which was obsolete in the 1920s!
- lmm 3y agoOn the contrary, as inverters and HVDC get cheaper, large synchronous grids are less worthwhile. Smaller grids are more resilient and easier to recover; that's the direction we're headed in, with plans to decouple some of these continental grids.
