Reactive power is the control then. With AC, we have to increase reactive power to shove more real power along the line, but reactive power doesn't transmit very well. Follow on: in a national grid, could we just distribute the production of reactive power with capacitor banks in each town / neighbourhood? Heavy flywheels spinning at 50hz? > building DC converter and switching stations is much more expensive than AC Is this intrinsic to the technology or is it more because we have economies of scale from building infrastructure around AC for 100 years? Thank you for this. Really helpful.
