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.

Claims

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 an energy reduction indication message type for announcing possible reductions of energy consumption; and

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.

2. The method of claim 1, wherein said energy managing control protocol further comprises an energy booking message type for announcing future energy consumptions and a granting message type for granting an energy booking message and/or an indication message.

3. The method of claim 1, wherein the method comprises the further steps of:

issuing a request message according to a request message type of the energy management control protocol to one or more energy consuming devices, the request message requesting the reduction or the increase of energy consumption; and

replying, at the one or more energy consuming devices , an indication message according to the energy reduction indication message type or a booking message according to the energy booking message type, respectively.

4. The method of claim 3, wherein the request message includes information about the requested reduction or increase of energy consumption, in particular specifies an energy consumption profile.

5. The method of claim 1, wherein the method comprises the further step of issuing, at an energy consuming device of the group of energy consuming devices , a booking message according to the energy booking message type for announcing changes in the future energy consumption behavior of the energy consuming device , when detecting a corresponding event, in particular a corresponding control command of the consumer.

6. The method of claim 1, wherein indication messages according to the energy reduction indication messages type include a priority indicator specifying how much the respective power consuming device is hindered by the indicated reduction of energy consumption.

7. The method of claim 1, wherein booking messages according to the energy booking message type include a priority indicator specifying how much the respective energy consuming device needs the indicated energy consumption.

8. The method of claim 1, wherein the energy management control device schedules energy consumption with respect to available energy assigned to the group of energy consuming devices and with respect to booking messages and indication messages received from energy consuming devices of the group of energy consuming devices, and wherein the energy management control device issues granting messages to the energy consuming devices according to the scheduling result.

9. The method of claim 1, wherein the energy consuming devices of the group of energy consuming devices constitute a self-organizing network of power consuming devices interacting via the energy management consumption control protocol, and wherein any of the energy consuming devices has a set of scheduling rules and negotiates its energy consumption according to these rules.

10. An energy consuming device of a group of energy consuming devices, the energy consuming device having a communication unit for communicating with other energy consuming devices of the group of energy consuming devices and/or with an energy management control device and/or with an energy management measuring device, a protocol handling unit for handling an energy management control protocol, the energy management control protocol comprising an energy booking message type for announcing future energy consumptions, 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 message, and a control unit for negotiating the energy consumption of the energy consuming device by means of the protocol handling unit and controlling the energy consumption of the energy consuming device according to the results of this negotiation.
