This would get rid of the frequency problems.

Basic physics. To run DC at the power levels required, the "wire" would have to be over 100 feet in diameter IIRC. Look up the Edison vs. Tesla
power arguments for all kinds of information on AC vs. DC.

What are the "required levels"? There is a 600 MW DC sea cable between Sweden and Germany with an outer diameter of about five inches (130 mm).
