Abstract

Claims (25)

1. A method for determining the thermal consumption of an energy system, wherein the energy system generates a total thermal energy within a time range, the method comprising:

determining a thermal charging energy of the energy unit within the time range;

determining a thermal discharging energy of the energy system within the time range; and

calculating a resulting thermal consumption within the time range by adding the total thermal energy to a difference between the ascertained thermal discharging energy and the ascertained thermal charging energy;

wherein the energy system includes a heat transfer medium within a thermal network, the heat transfer medium transported between a multiplicity of heat exchange elements and at least one thermal energy storage unit; and

determining the thermal charging energy of the energy system and the thermal discharging energy of the energy system includes consideration of a volume flow rate and a temperature of the heat transfer medium within the energy system.

2. The method as claimed in claim 1 , further comprising operating the energy system based on the calculated thermal consumption.

3. The method as claimed in claim 2 , wherein:

the thermal consumption is determined by an energy management system; and

the energy system is operated by the energy management system.

4. The method as claimed in claim 3 , wherein the calculated thermal consumption is used as a thermal load profile for a thermal load prediction of the energy management system.

5. The method as claimed in claim 4 , further comprising smoothing the calculated thermal consumption before using the consumption as a thermal load profile.

6. The method as claimed in claim 1 , wherein the energy system comprises a thermal network of the energy system.

7. The method as claimed in claim 6 , wherein determining the discharging energy and/or charging energy of the thermal network includes taking into consideration the volume and/or temperature of an outward flow and a return flow of the thermal network.

8. The method as claimed in claim 6 , wherein determining the thermal charging energy of the thermal network and/or the thermal discharging energy includes ascertaining a temperature difference between two different times.

9. An energy management system for operating an energy system and/or for predicting the thermal consumption of the energy system, wherein a total thermal energy is generated within a time range, the energy management system comprising:

means for determining a thermal charging energy of the thermal energy storage unit within the time range;

means for determining a thermal discharging energy of the thermal energy storage unit within the time range; and

means for calculating the thermal consumption within the time range by adding the total thermal energy to a difference between the ascertained thermal discharging energy and the ascertained thermal charging energy;

wherein the energy system includes a heat transfer medium within a thermal network, the heat transfer medium transported between a multiplicity of heat exchange elements and at least one thermal energy storage unit; and

determining the thermal charging energy of the energy system and the thermal discharging energy of the energy system includes consideration of a volume flow rate and a temperature of the heat transfer medium within the energy system.

10. The energy management system as claimed in claim 9 , wherein the energy system comprises a thermal network.

11. The energy management system as claimed in claim 10 , wherein:

the thermal network has an outward flow and a return flow;

the thermal charging energy and thermal discharging energy are ascertained through at least one measurement of a temperature of the outward flow and/or the return flow.
