Abstract :
The load recovery due to an aggregation of thermal loads controlled with thermostats after voltage variations of any size and duration is studied by using a physically-based model. Analytical expressions for the load recovery are deduced in the limit case of an aggregation of infinite structurally identical infinitesimal loads with a given total mean power. The analytical results are validated by comparison to stochastic simulations carried out on an aggregation of 10000 thermostatic loads. The results are used to explain some properties of the load recovery in the general case with random load parameters selected within a given range for a given probability distribution.
