There is a concept in temperature control called feed-forward.

In this case you would sample the supply line with an inverting
amplifier and use it to increase the oven drive signal as the
line voltage decreases. The goal is to keep the integral term
from changing as the line voltage changes. It is not as easy
as it sounds.
