Power production control system and method
View Patent ↗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.
1. A control system for an energy production facility, the system comprising:
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;
a processing unit included within 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 meet a 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;
wherein the plant controller provides a signal to a utility that indicates a ramp rate availability, wherein the ramp rate availability is calculated based on a relationship between a possible power of the energy production facility, a power set point, and a charge status of the energy storage device.
2. The control system of claim 1 , wherein the plant controller creates the signal causing the energy storage device to charge up until the energy storage device is fully charged.
3. The control system of claim 2 , wherein the power generators are wind turbine generators and further comprising:
a power collection system coupled to the wind turbine generators and the at least one energy storage device, the power collection system providing energy to the at least one energy storage device in one operational mode of the at least one energy storage device and receiving energy from the at least one energy storage device in an other operational mode of the at least one energy storage device.
4. The control system of claim 1 , further comprising:
a sensor coupled to the plant controller and to an output of the power production facility, the sensor providing the indication of the measured power output to the plant controller.
5. The control system of claim 4 , wherein the sensor also provides an indication of a frequency at the output of the power production facility to the plant controller.
6. The control system of claim 5 , wherein the plant controller creates a signal that causes power production devices coupled to the plant controller to vary operation based on the frequency at the output of the power production facility.
