Using planning to control demand response and supply choices in a managed electrical system

摘要

One embodiment of the present invention provides an energy-management system for managing energy within a predominantly closed power system. The system includes an identifying mechanism configured to identify a number of components coupled to the energy-management system, a receiving mechanism configured to receive current status information of the components, an evaluating mechanism configured to evaluate future energy need, a planning mechanism configured to plan future energy activities based on the energy need and the current status information, and a controlling mechanism configured to control operations of the components based on the planned energy activities.

1. A method for managing energy within a closed power system, comprising:
identifying a number of components within the closed power system coupled to an energy-management system, wherein the components include at least an energy supply and a load; receiving current status information of the components; evaluating a future energy need over a finite time horizon; computing, for the finite time horizon, a cost function which includes an energy-generation cost associated with the energy supply and a disutility associated with the load; calculating, for the finite time horizon, a deficit accumulated by the load during one or more demand response processes; planning future energy activities based on the energy need and the current status information to minimize the cost function, over the finite time horizon, subject to a constraint for reducing the deficit to zero by end of the time horizon; and controlling operations of the components based on the planned energy activities.
