Abstract

A method for controlling energy supply to different units includes receiving, by an aggregator, the demand request signal, and performing, by the aggregator, an allocation of the requested demand modification to the units based on a negotiating process with the units for minimizing an impact of the allocation on a future operation of another utility or of other utilities. Each unit is connected to multiple utilities for receiving enemy for operating its energy systems. A demand request signal is provided by at least one operational entity and/or by at least one utility for requesting a demand modification of a utility and/or of one form of energy.

Claims

1. A method for controlling energy supply to different units, wherein each unit is connected to multiple utilities for receiving energy for operating its energy systems and wherein a demand request signal is provided by at least one operational entity and/or by at least one utility for requesting a demand modification of a utility and/or of one form of energy, the method comprising:

receiving, by an aggregator, the demand request signal; and

performing, by the aggregator, an allocation of the requested demand modification to the units based on a negotiating process with the units for minimizing an impact of the allocation on a future operation of another utility or of other utilities.

2. The method according to claim 1, wherein the allocation is performed dynamically.

3. The method according to claim 1, wherein the negotiating process considers a prediction and/or a probability of one or more possible future demand modification requests of the utility and/or another utility or other utilities.

4. The method according to claim 3, wherein the prediction and/or probability depends on one or more of weather, time, season and/or activity,

5. The method according to claim 4, wherein the impact on a future operation of the another utility or other utilities comprises the impact on one or more possible and/or probable future demand modification requests of the another utility or other utilities.

6. The method according to claim 5, wherein the negotiating process considers feedback information from at least one unit and/or historical data and/or weather forecast.

7. The method according to claim 6, wherein the feedback information from a unit comprises an estimation of a maximal possible modification of the utility over a requested time period, wherein the modification is a reduction or an increase.

8. The method according to claim 6, wherein the feedback information from a unit comprises an estimation of how a maximal possible modification, of the utility over a requested time period would affect loads of other utilities that the unit is connected to, wherein the modification is a reduction of an increase.

9. A method according to claim 6, wherein historical data comprises prior allocation processes per unit including amount and/or timeline and/or duration of allocated demand modification.

10. A method according to claim 1, wherein the negotiating process considers a learned correlation between different utilities for at least one defined unit or for each unit in size or amount of allocated demand modification and/or of timely responsiveness.

11. A method according to claim 1, wherein the negotiating process considers an operation-specific priority level and/or a Key Performance Indicator requirement on a comfort level and/or scheduled operational conditions for activities or events.

12. A method according to claim 1, wherein the aggregator informs the units about allocated modifications.

13. A method according to claim 1, wherein the aggregator directly controls the energy systems of the units according to the allocated demand modification.

14. A method according to claim 1, wherein at least one unit is a building and/or wherein the at least one operational entity is an energy planning entity or a unit.

16. A method according to claim 2, wherein the allocation is performed in real-time.

15. A system for controlling energy supply to different units, wherein each unit is connected to multiple utilities for receiving energy for operating its energy systems and wherein a demand request signal is provided by at least one operational entity and/or by at least one utility for requesting a demand modification of a utility and/or of one form of energy, the system comprising:

an aggregator for receiving the demand request signal and performing an allocation of the requested demand modification to the units based on a negotiating process with the units for minimizing an impact of said allocation on a future operation of another utility or of other utilities.
