Integrated optimization and control for production plants

摘要

The present invention provides novel techniques for optimizing and controlling production plants using parametric multifaceted models. In particular, the parametric multifaceted models may be configured to convert a first set of parameters (e.g., control parameters) relating to a production plant into a second set of parameters (e.g., optimization parameters) relating to the production plant. In general, the first set of parameters will be different than the second set of parameters. For example, the first set of parameters may be indicative of low-level, real-time control parameters and the second set of parameters may be indicative of high-level, economic parameters. Utilizing appropriate parameterization may allow the parametric multifaceted models to deliver an appropriate level of detail of the production plant within a reasonable amount of time. In particular, the parametric multifaceted models may convert the first set of parameters into the second set of parameters in a time horizon allowing for control of the process plant by a control system based on the second set of parameters.

1. A system comprising:
a parametric multifaceted model of a process plant configured to receive inputs from the process plant, and to map a first set of parameters relating to a first facet of the parametric multifaceted model of the process plant into a second set of parameters relating to a second facet of the parametric multifaceted model of the process plant; an optimization system configured to optimize operation of the process plant using the second set of parameters and a first parameterized input/output control model, wherein the first parameterized input/output control model comprises a short-cut model; and a control system configured to control operation of the process plant using the first set of parameters and a second parameterized input/output control model, wherein the second parameterized input/output control model comprises a detailed dynamic model, wherein the first set of parameters is different than the second set of parameters and mapping the first set of parameters into the second set of parameters facilitates maintaining consistency between the first parameterized input/output control model and the second parameterized input/output control model, wherein the mapping of the first set of parameters into the second set of parameters is a function of current and/or anticipated operating conditions of the process plant and occurs over a time horizon during operation of the process plant allowing for control of the process plant.
