The grid is not unstable, Germany has a gigantic amount of batteries, flywheels, and giant resistors that can soak up the power, and is able to order wind farms and solar producers to curtail production if its still too much for the grid. Contrary to what a lot of folklore about Germany's grid suggests, these investments in stability are actually the primary reason Germany's electricity is so expensive compared to a lot of other countries

This is all actually beneficial. It creates real economic pressure for just about everyone to build and install more batteries everywhere to profit from the price swings.

Most importantly, it motivates the wind and solar producers to buy up batteries and install them on site, so that they can shift the times where they sell power to the grid to times of day where its more profitable.
