Power production control method based on power production rate requirement
First Claim
1. A method of operating a power production facility, the method comprising:
- receiving at a plant controller a current power production rate of the power production facility;
receiving a power production rate requirement at the plant controller from a utility receiving power from the power production facility;
determining at the plant controller that the current power production rate is either below or above the power production rate requirement;
transmitting a signal from the plant controller to cause a power producing device to charge an energy storage device in the event that the current power production rate is above the power production rate requirement or to cause the energy storage device discharge in the event that the current power production rate is below the power production rate requirement; and
providing a signal to the utility that indicates a ramp rate availability of the power production facility, the ramp rate availability being calculated based on a relation between a possible power of the power production facility, a power set point, and a charge status of the energy storage device.

Abstract
A control system for an energy production facility includes a plant controller for receiving an indication of a measured power output of the energy production facility that includes power generators and produces output signals. The system also includes a processing unit operably coupled to the plant controller and responsive to executable computer instructions when executed on the processing unit cause the plant controller to: create an output signal that causes an energy storage device to discharge in the event power reserves of the power generators can not met the requested ramp down rate; and create an output signal that causes the energy storage device to charge up in the event that the power capability of the power generators can meet the requested ramp down rate.
