Simplest way to make this technically feasible is to switch from AC grid to DC grid, which is not exactly small change.
On the other hand running your whole house on 290-310V DC is surprisingly simple (in places with 230V mains) beacause most typical home devices either don't care at all or have SMPS which rectifies mains voltage to DC. Probably only large-ish home appliance that needs AC is european-style (two knobs and big transformer) microwave oven.
