Abstract

In one embodiment, a policy coordination device receives soft policies from a plurality of localized energy consumption control devices, and examines the received soft policies to determine corresponding energy consumption. From this, the policy coordination device creates a global policy to reduce overall peak energy consumption between the received soft policies. As such, the policy coordination device transmits corresponding policy control commands to one or more of the plurality of localized energy consumption control devices based on the global policy. In another embodiment, a particular localized energy consumption control device discloses its soft policies and in response, receives a policy control command from the policy coordination device to control operation of one or more energy consuming devices (within soft limits of the soft policies) based on the global policy.
