What is usually the case with peak shaving systems? I would like to have ideas about how peak shaving generators are connected to the grid, how the system senses the peak load.

Is it possible to have the generators off and only come on when there is a peak demand and go off when the peak phases out?

Thanks in advance.

There's some useful information on the basics here:
