Power consumption management method

摘要

The invention concerns a method of managing energy consumed by a group of energy consuming devices ( 31 to 39 ) and energy consuming devices ( 31 to 36 ) for executing this method. Energy consuming devices ( 31 to 36 ) of the group of energy consuming devices exchange messages according to an energy management control protocol via a communication media ( 4 ). The energy management control protocol comprises an energy booking message type for announcing future energy consumption, an energy reduction indication message type for announcing possible reduction of energy consumption and a granting message type for granting an energy booking message and/or an energy reduction indication. The energy consuming devices ( 31 to 36 ) negotiate their energy consumption by means of the messages exchanged according to the energy management control protocol and control their energy consumption according to the result of this negotiation.
