System and approach to integrate and manage diverse demand response specifications for multi-site enterprises
First Claim
1. 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.

Abstract
A demand response system incorporating an enterprise demand manager (EDM), and a universal demand response gateway (UDG). The EDM may provide a single unified web interface. It may provide 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 may provide controls to the buildings based on market conditions, dispatch demand response (DR) events to the buildings, and provide feedback to confirm that requested reductions are occurring in the buildings. The DR events may include the buildings in an energy market, a load/energy reduction intensity level, and a target load/energy reduction amount for each building. The UDG may perform as a gateway between various DR automation servers (DRAS'"'"'s) and multiple supervisor controllers at the buildings.
