Abstract

Methods and systems are disclosed for managing a plurality of power resource assets from a central control center, operating the plurality of power resource assets in an automated fashion as a single power plant.

Claims (31)

1. A method for providing electrical power to a plurality of end-users of electricity, comprising:

receiving data in a central control center from each of the plurality of end-users, the data representing a demand for electrical power from each of the plurality of end-users;

determining a power output from each of a plurality of electric-power devices each capable of providing a maximum of approximately 10 megawatts of electrical power necessary to meet an aggregate of the demand for electrical power from each of the plurality of end-users based on the data from each of the plurality of end-users and operating characteristics of each of the plurality of electric-power devices, using only the central control center, to optimize the operation of at least one of the electric-power devices by at least one of: minimizing an operating expense of the at least one of the electric-power devices; maximizing a reliability of the at least one of the electric-power devices; minimizing a cost to produce electric power using the at least one of the electric-power devices; and maximizing an efficiency of the at least one of the electric-power devices; and

sending commands from the central control center to each of the plurality of electric-power devices to cause the plurality of electric-power devices to generate a combined power output equal to at least the aggregate of the demand for electrical power from each of the plurality of end-users.

2. The method of claim 1 , further comprising receiving operating data in the central control center from each of the plurality of electric-power devices, and determining a power output from each of the plurality of electric-power devices necessary to meet an aggregate of the demand for electrical power from each of the plurality of end-users based on the operating data.

3. The method of claim 1 , wherein the plurality of electric-power devices are located in separate geographic locations.

4. The method of claim 1 , wherein the plurality of electric-power devices comprise at least one of an emergency generator; a fuel cell; a photovoltaic cell; a reciprocating engine; a wind turbine; a microturbine; a battery; a super-conducting magnetic energy storage device; and a flywheel.

5. The method of claim 1 , wherein the plurality of electric-power devices comprise at least one of an electric power generator and an electric storage unit.

6. A system for providing electrical power to a plurality of end-users of electricity, comprising:

a communications network;

a plurality of electric-power devices each capable of providing a maximum of approximately 10 megawatts of electrical power;

a central control center in communication with the plurality of electric-power devices, wherein the central control center:

receives data from each of the plurality of end-users by way of the communications system, the data representing a demand for electrical power from each of the plurality of end-users;

exclusively determines a power output from each of the plurality of electric-power devices necessary to meet an aggregate of the demand for electrical power from each of the plurality of end-users based on the data from each of the plurality of end-users and operating characteristics of each of the plurality of electric-power devices, to optimize the operation of at least one of the electric-power devices by at least one of: minimizing an operating expense of the at least one of the electric-power devices; maximizing a reliability of the at least one of the electric-power devices; minimizing a cost to produce electric power using the at least one of the electric-power devices; and maximizing an efficiency of the at least one of the electric-power devices; and

sends commands to the plurality of electric-power devices by way of the communications network, the commands causing the plurality of electric-power devices to generate a combined power output equal to at least the aggregate of the demand for electrical power from each of the plurality of end-users.

7. The system of claim 6 , wherein the central control center further comprises:

at least one input device for at least one of receiving the data representing a demand for electrical power from each of the plurality of end-users and receiving operating data from the plurality of electric-power devices; and

a processor for exclusively determining the power output from each of the plurality of electric-power devices necessary to meet the aggregate of the demand for electrical power from each of the plurality of end-users based on the data from each of the plurality of end-users and operating characteristics of each of the plurality of electric-power devices.

8. The system of claim 7 , wherein the processor includes computer-executable instructions for:

receiving the data from each of the plurality of end-users;

determining the power output from each of the plurality of electric-power devices necessary to meet the aggregate of the demand for electrical power from each of the plurality of end-users; and

sending the commands causing the plurality of electric-power devices to generate a combined power output equal to at least the aggregate of the demand for electrical power from each of the plurality of end-users.

9. The system of claim 6 , further comprising a plurality of controllers for controlling operation of the plurality of electric-power devices in response to the commands sent to the plurality of electric-power devices by way of the communications network, and a plurality of communications devices for receiving the commands from the communications network and relaying the commands to the plurality of controllers.

10. The method of claim 6 , wherein the plurality of electric-power devices are located in separate geographic locations.

11. The method of claim 6 , wherein the plurality of electric-power devices comprise at least one of an emergency generator; a fuel cell; a photovoltaic cell; a reciprocating engine; a wind turbine; a microturbine; a battery; a super-conducting magnetic energy storage device; and a flywheel.

12. The method of claim 6 , wherein the plurality of electric-power devices comprise at least one of an electric power generator and an electric storage unit.

13. A computer-readable medium comprising computer-executable instructions for:

receiving data from each of a plurality of end-users of electrical power, the data representing a demand for electrical power from each of the plurality of end-users;

exclusively determining a power output from each of a plurality of electric-power devices having a maximum power-generating capacity of approximately 10 megawatts necessary to meet an aggregate of the demand for electrical power from each of the plurality of end-users based on the data from each of the plurality of end-users and operating characteristics of each of the plurality of electric-power devices, to optimize the operation of at least one of the electric-power devices by at least one of: minimizing an operating expense of the at least one of the electric-power devices; maximizing a reliability of the at least one of the electric-power devices; minimizing a cost to produce electric power using the at least one of the electric-power devices; and maximizing an efficiency of the at least one of the electric-power devices; and

sending commands to the plurality of electric-power devices for causing the plurality of electric-power devices to generate a combined power output equal to at least the aggregate of the demand for electrical power from each of the plurality of end-users.

14.
