Wind and solar energy are weather-dependent, which makes it almost impossible to estimate production, let alone control it in the event of additional demand. 20 years of electricity grid data reveals some surprises in this regard.https://www.notebookcheck.net/Study-investigates-relationship-between-renewable-energy-and-power-outages.928260.0.html
Do not seems a reliable study.
1-"On the other hand, long periods of heat show that coal- and nuclear power plants can no longer be reliably cooled. "
Rare and many countries do not have either but only fuel/gas power plants.
2- the number of production bottlenecks with renewable energy is several times those of fossil fuels. Lack of sun occurs each day, lack of wind much more often than an heatwave.

Remember Notebookcheck and many other mainstream press plus universities are subtly or outright pushing their agenda. You won't get accurate news from them.
California learned the hard way to keep their last and biggest nuclear power plant on after intense heat severely degraded their solar panels a few summers ago. Semiconductor devices like solar panels have upper junction temperature-related delimits just like CPUs.
The weather is not decentralised. Lack of sun does not occur is small isolated spots. So the drop in grid contribution is not as decorrelated as the study thinks.

Partly sunny, partly cloudy, mostly sunny, and mostly cloudy all literally mean, "Lack of sun DOES occur in small isolated spots"
