It's perfectly possible to have a stable grid even with solar and wind.
The problem is that neither nuclear nor coal power stations are load following and "base load" has lowered over the years (industry has moved to Asia, devices became more efficient, etc.).
Stand-by power (like natural gas powered generators) hasn't been built up the way the way it should have been. Same goes for smart grid technologies and buffer storage; not to mention the maniacs (especially in South Germany) who basically protest everything - from nuclear power, to wind power, to required infrastructure like north-to-south high-voltage transmission lines.
It's way too oversimplified to reduce the issue to just wind and solar.
