No, the voltage doesn't have to be higher. That's not how the AC power grid works.

You don't feed power into the system by trying to raise the voltage. You feed power into the system by trying to increase the frequency at the same voltage.

More accurately, you are advancing the phase which is roughly trying to increase the frequency and failing. The main system operators are detecting the very slight frequency increase and use that info to supply very slightly less power.
