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.
