Abstract
Systems and methods for implementing an economic strategy such as a model predictive control (EMPC) strategy. An EMPC tool is configured to present to receive sinks and connections between central plant equipment. The EMPC tool also includes a data model extender configured to extend a data model to define new entities and/or relationships. The EMPC tool also includes a high level EMPC algorithm configured to generate an optimization problem and an asset allocator configured to solve the resource optimization problem in order to determine optimal control decisions used to operate the central plant.
Claims20
An economic model predictive control (EMPC) tool comprising one or more non-transitory computer-readable media having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- comparing an input indicating a new entity or connection between entities of a central plant to a data model for the central plant to determine whether the new entity or connection is represented in the data model;
- in response to determining that the new entity or connection is not represented in the data model, extending the data model to define the new entity or connection;
- and
- using the data model with the new entity or connection in an EMPC control strategy to generate control decisions for the central plant.
A controller system, comprising:
- a processor configured to:
- receive an input indicating a new connection between entities of one or more buildings,
- extend a data model for the one or more buildings to include the new connection,
- provide an optimization problem using a high level economic model predictive control (EMPC) algorithm and the data model with the new connection, and
- solve the optimization problem to determine a set of control decisions using energy data, occupancy data, and weather data, the set of control decisions being for a building management system to control building equipment according to the set of control decisions.
A method for operating a central plant, the method comprising:
- comparing an input indicating a new entity or connection between entities of the central plant to a data model for the central plant to determine whether the new entity or connection is represented in the data model;
- in response to determining that the new entity or connection is not represented in the data model, extend the data model to include the new entity or connection;
- generating an optimization problem for the central plant using a high level EMPC algorithm and based on the data model with the new entity or connection;
- solving the optimization problem to determine a set of control decisions for the central plant, wherein the solving uses energy data, occupancy data, and weather data;
- and
- operating the central plant according to the set of control decisions.
