DC ties are very common when connecting difficult girds together; one of the main advantages is you dont have to sync with using them. You can also use them to flow power between 50hz and 60hz networks.
Yeah I was just abut to say this: with AC-DC-AC each side can make up their own sync and not worry about what the other is doing. The most well known example are the ones in Japan where one side of the country runs at 50Hz and the other at 60Hz.
