Power consumption management method
First Claim
1. A method of managing energy consumed by a group of energy consuming devices, the method comprising the steps of:
- exchanging messages according to an energy management control protocol via a communication media between energy consuming devices of the group of energy consuming devices and/or between energy consuming devices of the group of energy consuming devices and an energy management control device and/or an energy management measuring device, the energy management control protocol comprising indication messages of an energy reduction indication message type for announcing possible reductions of energy consumption, said indication messages including a priority indicator specifying how much the respective power consuming device is hindered by the indicated reduction of energy consumption;
negotiating the energy consumption of an energy consuming device of the group of energy consuming devices by means of the messages exchanged according to the energy management control protocol; and
controlling the energy consumption of the energy consuming device according to the result of this negotiation.

Abstract
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.
