If we integrate high levels of RE in the power system, what will happen when the sun doesn’t shine or the wind doesn’t blow.

RE can be variable (wind and PV) or dispatchable (hydro, bioenergy, geothermal and VRE with some storage). For a 100% RE grid, a mix of variable and dispatchable power is required. Storage can also be for different durations, eg 4 hours or seasonal. Further discussion on this topic is available in this Australian report:
