Re: A research team has managed to coordinate 100 domestic air conditioners to stabilise the power grid in real time, as if they were a flexible power plant.

My AC doesn't have a thermostat,

 Then how does it know when to run and not run?

It is not an ON/OFF thermostat, it is more likely a PID controller, probably implemented in software.
The result is that the compressor, once the target temp is reached, runs at low speed, matching the exact heat/cold wasted and maintaining a constant temperature. There is an inverter controlling the speed of the compressor.

 

it is continuously adjusted in tiny power adjustments with an inverter. Switching a thermostat on/off would destroy it.

 So, in winter, it still cools?

No, if powered the air would flow, but the compressor would be stopped. Actually, the user would push a button in the remote, and the unit would generate heat instead.
