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?

In a word, batteries.

We already know how to store energy for later use. Batteries do exactly that.

This is why renewable energy is not just about the actual devices collecting energy, like solar panels or wind turbines. You need a whole set of things, including batteries.
