Eli5: how will a power grid that is mostly powered by many non synchronous renewable generators (solar and wind etc) remain stable, when the stability of the grid is currently reliant on the collective inertia of the large scale base load generators of fossil fuel and nuclear power plants?

How can the grid remain stable today, when demand fluctuates daily and seasonally? There’s a lot of expensive infrastructure built to support it. Renewables will also need expensive infrastructure, it’ll just look and work a bit different.
Like, Solar meshes pretty well with daily needs. More demand during the daytime when the sun is out, so you get a fairly decent supply / demand match right there. If you over build solar you can then do things like charge cars during the day vs preferring nighttime charging.
