Systems and methods for performing building power management

A system for performing building power management for a building in response to a demand response event signal generated by an upstream demand response controller, the demand response signal including a payload, a demand response event begin time and a demand response event end time, comprising:

• a building automation system (BAS) constructed to send a plurality of commands to a plurality of electrical loads to control a power consumption of the plurality of electrical loads;
• a power manager having a BAS interface and a demand response controller interface, wherein the BAS interface is constructed to interface the power manager with the BAS;
• wherein the demand response controller interface is constructed to interface the power manager with the upstream demand response controller via a communication link and operative to receive the demand response event signal from the upstream demand response controller;
• wherein the power manager is constructed to:
• parse the demand response event signal;
• determine a power target based on the payload, the demand response event begin time and the demand response event end time;
• establish a power target tolerance bandwidth disposed about the power target;
• evaluate whether an average power consumption over a predetermined time period falls within, exceeds or falls below the power target tolerance bandwidth;
• access an action priority list that is constructed to prioritize the plurality of electrical loads;
• determine whether a shed action or a restore action is required, based on the evaluation and on the action priority list;
• determine which electrical loads of the plurality of electrical loads are to be shed or restored responsive to determining whether the shed action or the restore action is required;
• and providing a load control signal to the BAS, via the BAS interface, instructing the BAS that selected electrical loads of the plurality of electrical loads are to be shed or restored;
• and
• wherein the BAS is constructed to send at least some commands of the plurality of commands to selectively maintain, shed or restore the selected electrical loads responsive to the load control signal to control the power consumption of the building to fall within the power target tolerance bandwidth.

A system for performing building power management in response to a demand response event signal generated by an upstream demand response controller, comprising:

• an interface constructed to receive the demand response event signal from the upstream demand response controller for controlling a plurality of electrical loads, the plurality of electrical loads including variable electrical loads and fixed electrical loads;
• means for generating a load control signal instructing that selected electrical loads of the plurality of electrical loads are to be shed or restored, based on a power consumption falling within, exceeding or falling below power target tolerance bandwidth, and based on an action priority list constructed to prioritize the plurality of electrical loads, the action priority list being accessible by the means for generating the load control signal;
• and
• means for generating commands to selectively maintain, shed or restore each electrical load of the plurality of electrical loads based on the load control signal.
