Abstract

This invention is a system to control a network of distributed power machines. In one preferred embodiment, the system monitors the prices of electricity and hydrocarbon fuels on the open market. When the system determines that electrical power can be generated from a power machine like a fuel cell more cheaply than from a traditional source like coal-fired steam, the system sends an actuation command to the power machine network. The system also considers other factors, including load shedding arrangements, peak shaving arrangements, local rate structures, and the like. In another embodiment, the system includes a means for aggregating electrical power generated by power machines and selling it on an open market. The system also includes means for bill preparation and presentation. The system is capable of operating in several environments, including a traditional environment, a competitive environment, and a competitive environment.

Claims

1. A system for operating power machines, comprising:

a. a plurality of power machines, the power machines each comprising control circuitry coupled thereto; and

b. a remote means for actuating the power machines comprising;

i. a means for monitoring a market price of electricity;

ii. a means for monitoring a market price of hydrocarbon fuels; and

iii. a means for calculating the difference between the market price of electricity and the market price of hydrocarbon fuels;

wherein after the remote means for actuating the power machines transmits an actuation signal to the power machines, the control circuitry evaluates local data stored therein prior to actuating the power machines.

2. The system of claim 1, wherein the means for actuating the power machine network comprises means for transmitting an actuation signal across a communications means to a power machine.

3. The system of claim 2, wherein the actuation signal comprises a remote override signal causing the power machine to turn on or turn off.

4. The system of claim 3, further comprising a means for reading data from a meter.

5. The system of claim 4, further comprising a means for reading data related to the operational performance of the power machine.

6. The system of claim 5, further comprising a means for reading the local energy rate structure.

7. The system of claim 6, further comprising a means to calculate the load demand and to print and prepare a billing statement.

8. A system for generating power machine actuation data, comprising:

a. a plurality of power machines, the power machines each comprising control circuitry coupled thereto, wherein the control circuitry comprises;

i. a means for monitoring local data; and

ii. a means of considering electricity generation factors;

b. a remote means for actuating the power machines comprising;

i. a means of comparing the market price of electricity and hydrocarbon fuel;

ii. a means of transmitting an actuation signal; and

iii. a means of transmitting an override signal,

 

wherein the control circuitry evaluates the local data after receipt of the actuation signal;

 

further wherein the control circuitry omits evaluation of the local data upon receipt of the override signal.

9. The system of claim 8, further comprising a means for aggregating power to sell on a power market.

10. The system of claim 9, further comprising a means for generating a billing statement.

11. The system of claim 10, wherein the electricity generation factor is selected from the group consisting of market rate structure, peak shaving information, load shedding information and information relating to the ability to sell power to the grid.

12. The system of claim 11, wherein the system operates in an environment selected from the group consisting of a traditional environment, a transitional environment, and a competitive environment.

13. The system of claim 12, further comprising a means to calculate the load demand and to print and prepare a billing statement.

14. The system of claim 13, further comprising a means for selling power to the grid.

15. The system of claim 14, wherein the system participates in load shedding.

16. The system of claim 14, wherein the system participates in peak shaving.

17. The system of claim 14, wherein the data is selected from the group consisting of electricity prices, hydrocarbon prices, resource rate structure, power machine efficiency, power machine operating characteristics, futures prices, environmental data, regulatory rules, load demand, and weather.

18. The system of claim 13, further comprising a distributor capable of licensing the power machines.

19. The system of claim 14, wherein the distributor monitors the operational condition of the power machines.
