Abstract

Provided is a system and method for monitoring utilization of a resource across an entire distribution area. The system dynamically and intelligently limits the aggregated utilization of the resource across an entire distribution area or targeted sub areas. Targeted usage thresholds at the device (individual utilization) level, as well as utility-specified business and technical rules and overrides, can be applied. Using these rules, the system continuously looks for and manages individual utilization of the resource that is available for curtailment, thus producing a larger and more efficient utilization level that is available for reduction without service impact to customers within that service area or targeted sub areas.

Claims

1. A method of managing utilization and distribution of a utility resource, the method comprising:

monitoring condition parameters of individual customer premises that pertain to utilization of said resource, to obtain respective condition values;

storing the obtained condition values in a database by ID of the customer premises and storing predefined service parameters of respective customer premises; and

controlling utilization of said resource by devices located at the customer premises based on predefined priority parameters, the condition values, and the predefined service parameters.

2. The method of claim 1, wherein the condition values include at least one of temperature, internal ambient temperature, device state, device voltage, device current, power factor, and resource utilization profile.

3. The method of claim 2, wherein the devices are categorized into different types and the condition parameters depend on the type of the device.

4. The method of claim 1, wherein the predefined priority parameters are based on at least one of type of device, customer priority, and customer preferences.

5. The method of claim 1, wherein the predefined service parameters include at least one of physical address, customer preferences, customer shed priority, and device priority.

6. The method of claim 1, wherein the monitoring is performed by using premise sensors and premise controllers, the premise sensors being configured to detect the condition values of respective devices and the premise controllers being associated with respective devices.

7. The method of claim 6, wherein the premise sensors and the premise controllers are configured to work cooperatively with each other.

8. The method of claim 7, wherein the premise sensors and the premise controllers are integrated.

9. The method of claim 6, wherein based on data from the premise sensors, the premise controllers are operated to reduce utilization of said resource by respective devices.

10. The method of claim 6, further comprising:

obtaining the condition values by polling the premise sensors.

11. The method of claim 6, wherein the sensors autonomously transmit the condition values.

12. The method of claim 1, wherein the obtained condition values are correlated with the predefined service parameters.

13. The method of claim 1, further comprising:

establishing a maximum level of resource demand across an entire resource distribution grid, subareas within the grid, or individual customer premises.

14. The method of claim 13, wherein when the utilization of said resource reaches the maximum level of system demand, a cumulative total of the utilization by all devices that are running is calculated and a desired utilization level is compared with the running cumulative total to obtain a desired reduction amount, a curtailment in utilization of said resource being initiated if the desired utilization level is lower than the running cumulative total.

15. The method of claim 14, further comprising:

establishing priority levels for the individual customer premises; and

selectively controlling the devices at the customer premises based upon the priority level.

16. The method of claim 15, further comprising:

creating groups of devices, according to their priority level, whose total utilization of said resource matches the desired reduction amount; and

sending a command to each premise controller of the group with the lowest priority level to signal the premise controller to interrupt delivery of said resource to the respective device.

17. The method of claim 16, wherein a subsequent group with the next lowest priority level is selected and a command is sent to each premise controller of the group to signal the premise controller to interrupt delivery of said resource to the respective device, the curtailment in utilization of said resource being implemented from lowest priority level to highest priority level until the curtailment in utilization is satisfied.

18. The method of claim 16, wherein each group includes at least one device as a member.

19. The method of claim 16, wherein the premise controller sends a time stamped response to notify that the delivery of said resource to the device has been interrupted.

20. The method of claim 19, wherein the amount of the utilization of said resource that was curtailed is determined by comparing the change of state of the device to the previous utilization of said resource by the device.

21. The method of claim 14, further comprising:

monitoring the desired utilization level and the utilization by all of the devices until utilization curtailment is no longer needed, wherein when a device reaches a value of at least one of the predefined service parameters, a command is sent to the respective premise controller of the group to signal the premise controller to restore delivery of said resource to the interrupted device.

22. The method of claim 4, wherein customer priority is based on criteria including amount of time the device has been manipulated and amount of time said resource has not been supplied to the device.

23. The method of claim 4, wherein customer preferences are based on criteria including at least one of monthly budget limits and ambient house temperature.

24. The method of claim 1, wherein an aggregated utilization of said resource is managed and dynamically limited across at least one of an entire distribution area, targeted subareas, and individual customer premises.

25. The method of claim 6, further comprising:

communicating between an enterprise management platform and the premise controllers and premise sensors in a mesh network.

26. The method of claim 25, wherein the premise controllers are controlled wirelessly via radio signals and the premise sensors transmit data wirelessly.

27. The method of claim 25, wherein the premise controllers and premise sensors are grouped together and each group communicates with the enterprise management platform via an aggregator for the group.
