Low-frequency ancillary power grid services
First Claim
1. A method of providing ancillary services to a power grid using a customer premises comprising at least one power consumption component, the method comprising:
- receiving a regulation signal; and
based on the received regulation signal, modifying at least one operating parameter of a single power consumption component so that a projected power consumption by the single power consumption component is changed in accordance with a projection of the received regulation signal,wherein the regulation signal is associated with an ancillary service for the power grid and indicates a change in power consumption at the customer premises to implement the ancillary service.

Abstract
Techniques for providing ancillary services to a power grid using customer premises such as commercial buildings. The techniques may involve receiving a regulation signal from a grid operator that is specific to a commercial building and modifying power consumption by at least one power consumption component in the building based on the regulation signal. The power consumption component may be a fan and/or a chiller of a Heating, Ventilation, and Air Conditioning (HVAC) system. The regulation signal may be tracked in a at least a portion of a frequency band from about 4 seconds to about 60 minutes, and the control architecture may depend on the portion of the frequency band.

11. A method of providing ancillary services to a power grid using a customer premises comprising at least one power consumption component, the method comprising:
-
receiving a regulation signal; determining primary frequency components of the regulation signal; and based on the primary frequency components, selecting at least one operating parameter of a single power consumption component and adjusting the at least one selected operating parameter so that power consumption by the single power consumption component is changed in accordance with the received regulation signal, wherein the regulation signal has primary frequency components indicative of variations in power consumption over a time ranging from 4 seconds to 120 minutes. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for operating a power grid, the method comprising:
-
determining an amount of load to be adjusted in the power grid; allocating to each facility of a plurality of facilities an adjustment in power consumption to achieve a load adjustment based on the determined amount; and transmitting a plurality of regulation signals to the plurality of facilities, wherein each regulation signal of the plurality of regulation signals transmitted to the facility indicates the adjustment in power consumption allocated to the facility. - View Dependent Claims (23, 24, 25, 26)
