Well the higher the frequency the more efficient transformers are, and can
be smaller as witnessed by switch mode supplies.
I think for distribution reasons, the delivery would still be AC though.
As a matter of interest, those who use the high voltage DC grids, how do
they convert to AC when needed. have to be one large inverter!
No that's incorrect.
Higher frequency = smaller physical sized motors & transformers but greater
losses.
Aircraft run on high frequency power to save weight.
HF smpsu transformers have much lower copper losses & total losses than 50Hz iron lumps.
Actually they don't.
