BUILDING CONTROL SYSTEMS WITH OPTIMIZATION OF EQUIPMENT LIFE CYCLE ECONOMIC VALUE WHILE PARTICIPATING IN IBDR AND PBDR PROGRAMS
First Claim
1. A central plant configured to generate and provide resources to a building, the central plant comprising:
- an electrical energy storage subplant configured to store electrical energy purchased from a utility and to discharge the stored electrical energy;
a plurality of generator subplants configured to consume one or more input resources comprising the discharged electrical energy and to generate one or more output resources to satisfy a resource demand of the building; and
a controller configured to determine, for each time step within a time horizon, an optimal allocation of the input resources and the output resources for each of the subplants in order to optimize a total monetary value of operating the central plant over the time horizon.

Abstract
A central plant includes an electrical energy storage subplant configured to store electrical energy, a plurality of generator subplants configured to consume one or more input resources, including discharged electrical energy, and a controller. The controller is configured to determine, for each time step within a time horizon, an optimal allocation of the input resources. The controller is configured to determine optimal allocation of the output resources for each of the subplants in order to optimize a total monetary value of operating the central plant over the time horizon.
