Intelligent metering demand response

摘要

A system and method for real-time power management are provided. The system can include one or more lights, one or more light controllers, one or more meters to detect power demand of a building, and a central controller to modify the light output of the lights responsive to the detected power demand. The system can interface with other utility controls to manage the total power demand of the building on a real-time basis. The light controllers can provide individual metering of the lights for use by the central controller.

1. A system for managing utility services in a building, the system comprising:
at least one building load; at least one utility meter to measure an amount of power consumed within a building and to output demand data corresponding to the amount of power consumed within the building; at least one sub-meter to measure an amount of power consumed by the at least one building load; at least one building load controller to control power to the at least building load, wherein the at least one building load controller can control the at least one of building load; and a central controller to receive the demand data from the at least one sub-meter or the at least one utility meter and to send a signal to the building load controller to adjust the at least one of building load in response to the demand data, wherein the central controller is configured to maintain the amount of power consumed within the building below a power setpoint set by a user or utility company such that the amount of power consumed within the building does not exceed the power setpoint, wherein the central controller is configured to receive a new power setpoint from the at least one sub-meter or the at least one utility meter and to adjust the amount of power consumed within the building such that the amount of power consumed within the building does not exceed the new power setpoint; and wherein the building load controller modifies the at least one building load by turning the at least one building load on or off or by reducing power to the at least one building load.
