Day-ahead scheduling and real-time Economic MPC of CHP unit in Microgrid with Smart buildings

This paper presents a model for day-ahead scheduling of the CHP heat and electric energy production for a residential Microgrid taking into account the economic factors in a liberalized electricity markets, the technical factors in the safety/quality of supply, and the consumer preferences. This day-ahead scheduling model is complemented with a real-time economic MPC model for a subsequent control with respect to the outcomes of the day-ahead scheduling. This combined scheduling and economic MPC provides a general set-up capable of overcoming several major difficulties encountered with a typical scheduling + tracking MPC set-up, e.g. the problems of connecting the economic objectives with different temporal resolution and different requirements in terms of delivery.
