We can also time shift many of the things we do. Does your fridge need to run between 3-5pm in the heat of summer? or can it make sure its a little cooler to avoid running then? (trivial example, probably not a good one)

I'm sure there are better examples, but your fridge idea doesn't work. Fridges already operate on the edge of freezing, so if you make it a little cooler you will ruin all your food. Also 3-5pm is peak hangry time.
A modern fridge also uses approximately five watts, on average. There are far better targets.
good thing the grid cares about long term average real power and not instanaenous reactive power then.
Demand response for things like hotel air conditioning is a thing: https://www.bbc.co.uk/news/science-environment-23343211
Batteries are also getting cheaper and cheaper
This is why a major part of the solution is electric vehicles. Why put batteries in a warehouse and then run vehicles on petroleum when you can put batteries in a vehicle, install twice as many renewables because you now have more demand for electricity, and then charge the vehicles when generation is a large percentage of rated capacity and still have enough to run the rest of the grid when it's a smaller percentage?
And they are the only real solution. Demand fitting production is never going to work unless we give up all the autonomy.
It will be a mix. There is certainly still a lot which can be done on the demand side, e.g. when to cool a cool storage house during the day, or when to run certain production lines.
