System and approach to integrate and manage diverse demand response specifications for multi-site enterprises

A demand response (DR) system comprising:

• an enterprise demand manager (EDM);
• and
• a universal demand response gateway (UDG);
• and
• wherein:
• the EDM provides a single unified web interface;
• the EDM provides a cloud application that allows an operator of an enterprise to create and send load/energy reduction requests to buildings of one or more groups of buildings in the enterprise;
• the cloud application provides controls that are predefined and sent to the buildings based on market conditions, and controls to allow an operator to dispatch a demand response (DR) event to the buildings, and provide feedback to confirm that requested reductions are occurring in the buildings,
• upon dispatch of a load/energy reduction program, the DR automation server (DRAS) sends the DR event message to the buildings programmed for the load/energy reduction program;
• and
• a building automation system (BAS) receives the DR event message via the UDG and interprets the DR event message and invokes load/energy reduction control strategies of the load/energy reduction program;
• the DR event includes the buildings in an electricity market, a load/energy reduction intensity level, and a target load/energy reduction amount for each of the buildings;
• and
• the UDG performs one or more items selected from a group comprising acting as a gateway between various DR automation servers (DRAS's) and multiple supervisor controllers at the buildings, allowing the buildings to be registered with a DRAS which permits the buildings to be included in the load/energy reduction program, providing a mechanism to map supervisory controllers at the buildings, and integrating a DRAS from different aggregators to the buildings,
• wherein an operator pre-defines load/energy reduction request groups (DR events) that contain buildings which participate within specific electricity markets along with a target load/energy reduction amount for each building.
