How it works in the UK at the moment is there are particular times when the grid knows it is going to be under severe load. Typically it gives about 6 hours warning. Consumers can then charge up their batteries from the grid and reduce load/force discharge during a (usually) 1 or 2 hour slot. It's designed to reduce the need to crank up old coal-fire power stations. I realise this a bit different to the every day duck-curve, but interesting nonetheless
