System And Method For Generating And Providing Dispatchable Operating Reserve Energy Capacity Through Use Of Active Load Management

A utility employs a method for generating available operating reserve. Electric power consumption by at least one device serviced by the utility is determined during at least one period of time to produce power consumption data, stored in a repository. A determination is made that a control event is to occur during which power is to be reduced to one or more devices. Prior to the control event and under an assumption that it is not to occur, power consumption behavior expected of the device(s) is generated for a time period during which the control event is expected to occur based on the 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 the devices' power consumption behavior. An amount of available operating reserve is determined based on the projected energy savings.

  • Claim 1. A method for supplying operating reserve for an electric power grid comprising: determining amounts of electric power stored by devices located at one or more servicepoints to produce stored power datastoring the stored power data in a repositorycharacterizing each power consuming device in a set of power consuming devices as environmentally-independent or environmentally-dependentprojecting energy savingsfrom the set of power consuming devices based on an actual value corresponding to a reduction in consumed power by each power consuming device with measurement and verification, wherein the actual value is a monetary supply equivalent value providing acurtailment value as a supply presented to and accepted by a governing entity for awarding each power consuming device supply equivalencedetermining an amount of available operating reserve based on at least the stored power data and the projectedenergy savingsreceiving a request for an operating reserve from a utility and/or a market participant of the electric power gridand responsive to the request for the operating reserve, managing a flow of electric power from the devices to theelectric power grid and from the electric power grid to the set of power consuming devices to provide the operating reserve based on the amount of available operating reserve.
  • Claim 9. A method for supplying operating reserves for at least one grid operator on an electric power grid comprising: determining an amount of electric power stored by at least one device at a service pointcharacterizing each power consumingdevice in a set of power consuming devices as environmentally-independent or environmentally-dependentprojecting energy savings from the set of power consuming devices based on an actual value corresponding to a reduction in consumed power by eachpower consuming device with measurement and verification, wherein the actual value is a monetary supply equivalent value providing a curtailment value as a supply presented to and accepted by a governing entity for awarding each power consuming devicesupply equivalencereporting the amount of stored power and the projected energy savings to a controllerand controlling a flow of electric power from the at least one device to a power grid accessible by the at least one grid operator and/or fromthe power grid to the set of power consuming devices responsive to a request from the controller for the operating reserves by the at least one grid operator and based on at least the amount of electric power stored and the projected energy savings.
  • Claim 19. A method for providing operating reserves for at least one grid operator of an electric power grid comprising: receiving a request for operating reserve from the at least one grid operator of the electric power griddetermining andaggregating amounts of electric power stored by devices associated with at least one service point on the electric power gridgenerating stored power data and corresponding revenue grade metrology for the amounts of electric power stored by the devicesavailable as operating reservesprojecting energy savings from a set of power consuming devices based on an actual value corresponding to a reduction in consumed power by each power consuming device resulting from a control event with measurement andverification, wherein the actual value is a monetary supply equivalent value providing a curtailment value as a supply presented to and accepted by a governing entity for awarding each power consuming device supply equivalenceand managing a flow ofelectric power from the devices, via a control device associated with one of the devices, to the electric power grid and/or managing a flow of electric power from the electric power grid to the set of power consuming devices to provide the operatingreserve based on the stored power data and the projected energy savings.
