Correlation identification of alternating renewal electric load models

An identification algorithm for a previously proposed stochastic hybrid-state Markov model of individual heating-cooling loads is presented. It relies on data of a kind routinely gathered in power systems (device energy consumption over constant time intervals). It exploits an alternating renewal viewpoint of the load dynamics. After deriving some general results on alternating renewal processes, the authors focus on the specific model. Some features likely to be shared by a wide class of alternating renewal processes are revealed. Simulation results are presented
