Abstract

A method for energy management optimizes loads and sources in an energy management network and includes at least one energy management unit. The actual state of the energy consumers and energy sources is transferred to the energy management unit by means of combined energy supply and communication lines. An independent configuration of the energy management unit is performed, and at least one target parameter is set on the energy management unit.

Claims

1. A method for energy management for optimizing loads and generation in an energy management network which has at least one energy management unit, comprising:

transmitting the ACTUAL state of the electrical loads and of the energy generators via combined electricity supply/communication lines to the energy management unit;

performing autonomous configuration of the energy management unit; and

setting at least one TARGET parameter on the energy management unit.

2. The method as claimed in claim 1, further comprising:

localizing the electrical loads and the energy generators in the energy management network by means of an indexed appliance type and the knowledge of typical setup locations for these terminals in the energy management network.

3. The method as claimed in claim 1, further comprising:

localizing the electrical loads and the energy generators in the energy management network by means of determination of propagation times for signals via the combined electricity supply/communication lines.

4. The method as claimed in claim 1, further comprising:

localizing the electrical loads and the energy generators in the energy management network by means of radio location.

5. The method as claimed in claim 1, further comprising:

selecting a plurality of TARGET parameters on a user-specific basis; and

setting the plurality of TARGET parameters with a weighting relative to one another.

6. The method as claimed in claim 5, wherein the TARGET parameters prescribed are a value for energy costs, a value for CO₂ emission and a convenience value, respectively.

7. The method as claimed in claim 1, further comprising:

recognizing the type and the ACTUAL state of the electrical loads and of the energy generators in the energy management network from the switching characteristics of said loads and generators; and

ascertaining a consumption per unit time.

8. The method as claimed in claim 1, further comprising:

measuring the ACTUAL state of the electrical loads and of the energy generators in the energy management network with induction clamps; and

performing injection into the combined electricity supply/communication lines with induction clamps.

9. The method as claimed in claim 1, further comprising:

evaluating additional sensor data from sensors which are connected directly by means of intermediate receptacles between the electrical loads and on the energy generators and the combined electricity supply/communication lines or which transmit their information wirelessly thereto by the energy management unit.

10. The method as claimed in claim 1, further comprising:

evaluating additional sensor data from radio-based sensors which send their data to reception appliances within the energy management network or directly to the energy management unit.

11. The method as claimed in claim 1, further comprising:

sending signals to actuators connected to the electricity supply/communication lines with the energy management unit; and

/or

sending radio-based signals to actuators in the energy management network with the energy management unit.

12. The method as claimed in claim 1, further comprising:

implementing bidirectional data transfer to external data systems using a data access interface integrated in the energy management network; and

performing the data transfer in wired and/or radio-based fashion.

13. An apparatus for energy management comprising:

at least one energy management unit configured to optimize loads and generation in an energy management network,

wherein the energy management unit includes devices for receiving an ACTUAL state of the electrical loads and of the energy generators,

wherein the ACTUAL state can be transmitted via combined electricity supply/communication lines to the energy management unit, and hence autonomous configuration of the energy management unit can be implemented, and

wherein at least one TARGET parameter can be set on the energy management unit.

14. The apparatus as claimed in claim 13, wherein the energy management unit further includes reception and/or transmission devices for radio-based information from and to sensors and/or actuators positioned in the energy management network.

15. The apparatus as claimed in claim 13, wherein:

the TARGET parameter(s) can be set mechanically or electronically by means of control sliders using touch user interfaces, and

the TARGET parameters and the ACTUAL state of the electrical loads and of the energy generators in the energy management network can be presented via a display.
