Well... strictly speaking, it's your utility company might use a
capacitor bank to minimize a drop in line voltage, but that's only if
you are having problems with low power factor and that is generally
not a problem with residential service unless you live in a factory
district. In most cases, it's a power company problem and there are
few, if any residences that switch in capacitance to correct for low
power factor.
A brownout is an extended-time drop in voltage to your service usually
caused by heavy loads (like summer-time peak air conditioning).
There is not much you can do about them unless you have a line
conditioner, which might also be described as a variable buck-boost
transformer that effectively changes taps on-the-fly. Some power
company substation transformers will do this for you. Not sure what
you mean by buffering capacitance unless you are speaking in a very,
very general sense, as in the stored energy of a ferro-resonant
transformer or a mechanical flywheel.
