These are called ancillary services. There are 3 levels: frequency control (for example dams), primary reverse (fast acting power, in less than 10s), and secondary reserve (slow acting: < 15min).
Participants can either be positive (they consume more energy, for example PHES systems), or negative (they inject or consume less energy).
All these ancillary services are paid (annual auction + per case). Nowadays, it's getting bigger with VPP: virtual power plants, which aggregate small loads (i.e. small ~1MW generators) in order to propose a bigger load to TSOs.

On top of that, newer solar inverters MUST (at least in the EU) reduce power if frequency rises in order to automatically shed power in cases of extreme supply

It's all automatic
