Demand Response Using Service Curves

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We propose an alternative approach, based on ``service curves", which uses the following two ingredients. (1) The rate at which a consumer may draw power from the grid may be controlled by real time signals. Typical concerned devices would be heating syste ...
