SYSTEM AND METHOD FOR GENERATING AND PROVIDING DISPATCHABLE OPERATING RESERVE ENERGY CAPACITY THROUGH USE OF ACTIVE LOAD MANAGEMENT TO COMPENSATE FOR AN OVER-GENERATION CONDITION
First Claim
1. A method for assisting in providing frequency regulation of electric power supplied to an electric power grid to one or more service points to compensate for an over-generation condition, wherein a grid operator or apparatus or systems utilized by the grid operator performs the steps comprising:
- determining amounts of electric power consumed by at least one device during predetermined time intervals as specified by regulations governing operations of the electric power grid to produce power consumption data, the at least one device being located at the one or more service points;
storing the power consumption data in a data repository;
determining that a control event is to occur, wherein a supply of electric power to the at least one device is increased for providing grid stability;
determining, prior to commencement of the control event, power consumption behavior of the at least one device for a predetermined future time period based at least on the stored power consumption data; and
determining, prior to commencement of the control event, projected energy consumption resulting from the control event based the power consumption behavior of the at least one device and a power supply value (PSV) associated with the at least one device.

Abstract
A utility employs a method for generating available operating reserve. Electric power consumption device(s) serviced by the utility is determined during period(s) 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.

39. A system that assists in providing frequency regulation of electric power supplied to an electrical grid to one or more service points to compensate for an over-generation condition, each service point including at least one device that consumes power during operation thereof, the system comprising:
-
an electronic repository; and at least one processor coupled to the repository, the at least one processor operable to; determine amounts of electric power consumed by the at least one device during at least one period of time to produce power consumption data; store the power consumption data in the repository; determine that a control event is to occur during which a supply of electric power is to be increased to the at least one device even though the at least one device is not in need of an increase in electric power, the control event serving to assist in providing frequency stability to the electrical grid; generate, prior to commencement of the control event, power consumption behavior of the at least one device for a predetermined future time period based at least on the stored power consumption data, wherein the control event is expected to occur at some time during the predetermined future time period; generate a power supply value (PSV) associated with each of the at least one device; and determine, prior to commencement of the control event, projected energy consumption resulting from the control event based at least on the power consumption behavior of the at least one device and the PSV associated with the at least one device. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. A virtual utility system operable to assist in regulating frequency of electric power supplied by a power-generating utility and/or any market participant associated with an electric power grid during an over-generation condition, the virtual utility system comprising:
-
an electronic repository; and at least one processor coupled to the repository, the at least one processor operable to; determine amounts of electric power consumed by at least one device during at least one period of time to produce power consumption data, the at least one device being located remotely from the at least one processor; store the power consumption data in the repository; receive at least one control message from the power-generating utility or any market participant associated with the electric power grid, the at least one control message requesting a decrease in electrical energy supplied by the power-generating utility to an electrical grid; responsive to the at least one control message, determining that a control event will occur, wherein a supply of electric power is to be increased to the at least one device, for providing grid stability to electric power supplied by the power-generating utility and/or any market participant associated with the electric power grid; determining, prior to commencement of the control event, power consumption behavior and/or a power supply value (PSV) associated with the at least one device for a predetermined future time period based at least on the stored power consumption data, wherein the control event is expected to occur at some time during the predetermined future time period; determine, prior to commencement of the control event, projected energy consumption resulting from the control event based at least on the power consumption behavior of the at least one device and the PSV associated with the at least one device; determine, prior to commencement of the control event, whether the projected energy consumption is sufficient to meet the decrease in electrical energy requested by the power-generating utility and/or any market participant associated with the electric power grid; and manage delivery of electric power to the at least one device during the control event to provide grid stability. - View Dependent Claims (51, 52)
