System and method for estimating and providing dispatchable operating reserve energy capacity through use of active load management
First Claim
1. A method for a client device located at an electrical service point to control a flow of electric power from an electric power grid to the service point so as to provide operating reserve to the electric power grid, the service point including at least one power consuming device operable to consume electric power, at least one controllable device operable to control a flow of grid-supplied electric power to the at least one power consuming device, and a backup power subsystem operable to supply electric power to the at least one power consuming device when a flow of grid-supplied electric power to the at least one power consuming device is reduced below a threshold, the method comprising:
- receiving power control messages from a remote system control component, at least a first power control message instructing the client device to disable a flow of grid-supplied electric power to the at least one power consuming device; and
providing a first power control instruction to the at least one controllable device responsive to the first power control message, the first power control instruction instructing the at least one controllable device to disable a flow of grid-supplied electric power to the at least one power consuming device, thereby causing activation of the backup power subsystem, wherein an amount of grid-supplied electric power saved as a result of disabling a flow of grid-supplied electric power to the at least one power consuming device provides operating reserve for the electric power grid based upon a power supply value (PSV) associated with each of the at least one power consuming device(s).

Abstract
A method for generating a value for available operating reserve for electric utility. Electric power consumption by at least one device is determined during at least one period of time to produce power consumption data, stored in a repository. Prior to a control event for power reduction and under an assumption that it is not to occur, power consumption behavior expected of the device(s) is determined for a time period during which the control event is expected to occur based on stored power consumption data. Additionally, prior to the control event, projected energy savings resulting from the control event, and associated with a power supply value (PSV) are determined based on devices'"'"' power consumption behavior. Amount of available operating reserve is determined based on projected energy savings.

6. A method for a subsystem located at an electrical service point to reduce consumption of electric power supplied from an electric power grid to a service point, the subsystem including a client device in communication with a remotely located system control component and operable to control a flow of grid-supplied electric power to at least one power consuming device located at the service point, and a backup power subsystem operable to supply electric power to the at least one power consuming device when a flow of grid-supplied electric power to the at least one power consuming device is reduced below a threshold, the method comprising:
