Hi
My take on this is SMPS will pull more current when the volts drop for a given load. This is the same on electric 13a vehicle chargers as far as I can see reading specs. As others have mentioned resistive loads like kettles will take longer to heat. Bear in mind that when the voltage was reduced in the 70s there was no SMPS in domestic applications. Some inductive motors that use run caps always run at the same RPM and with a fixed load will also draw more current with lower volts.
IMHO not a solution, best idea is to switch off appliances when not in use, remove chargers, unused clocks, lights, and anything that is unnecessary, I think we all should now know what to do.
