Abstract
In accordance with one embodiment, a system for non-intrusive load monitoring includes an output device, a data storage device including program instructions stored therein, a sensing device operably connected to a common source for a plurality of electrical devices, and an estimator operably connected to the output device, the data storage device, and the sensing device, the estimator configured to execute the program instructions to obtain data associated with a sensed state of the common source from the sensing device, obtain at least one model of each of the plurality of electrical devices, solve a Mixed Integer Programming problem for the at least one models over a fixed time horizon using the obtained data to determine a combination of operational stages of the plurality of electrical devices, and store operational data based on the solved Mixed Integer Programming problem.
