Decentralized Demand Response for Temperature-Constrained Appliances

We study the demand-response potential from large numbers of appliances which have to maintain some temperature within a fixed range through the ON/OFF functioning of a temperature modifier. Based on a mathematical model, we propose methods to coordinate appliances to offer a global energy demand reduction over an imposed duration while still satisfying the appliances' temperature constraints, and with limited communication overhead. The maximum power reduction that can be attained is expressed mathematically, as a function of the appliances' specificities and the reduction duration asked by the grid.
