Method for controlling an exchange of energy in an energy system, control center, energy system, and storage medium

An energy system comprising:

• multiple control units for controlling a respective energy subsystem with regard to an exchange of energy between the respective energy subsystem and one or more other energy subsystems;
• and
• a control center programmed to:
• receive first supply data from a first energy subsystem, wherein the first supply data represent respective remuneration conditions of the first energy subsystem for receiving and/or providing energy;
• transmit the first supply data to a second energy subsystem;
• receive second supply data adapted based on the first supply data, from the second energy subsystem, wherein the second supply data represent respective remuneration conditions of the second energy subsystem for receiving and/or providing energy;
• and
• controlling the exchange of energy between the first energy subsystem and the second energy subsystem based on the first supply data and second supply data;
• wherein the first supply data are determined by the first energy subsystem on the basis of a system state of the first energy subsystem and/or the second supply data are determined by the second energy subsystem on the basis of a system state of the second energy subsystem;
• calculating a divergence between a previously forecast system state for a time interval and a system state determined later for the same time interval;
• and
• at least one of the first supply data and the second supply data are determined so the divergence is minimized.

A non-transitory storage medium having a computer program stored thereon, the computer program comprising instructions which, when loaded and executed by a control center, cause the control center to control an exchange of electrical energy by:

• receiving first supply data from a first energy subsystem, wherein the first supply data represent respective remuneration conditions of the first energy subsystem for receiving and/or providing energy;
• transmitting the first supply data to a second energy subsystem;
• receiving second supply data adapted based on the first supply data, from the second energy subsystem, wherein the second supply data represent respective remuneration conditions of the second energy subsystem for receiving and/or providing energy;
• and
• controlling the exchange of energy between the first energy subsystem and the second energy subsystem based on the first supply data and second supply data;
• wherein the first supply data are determined by the first energy subsystem on the basis of a system state of the first energy subsystem and/or the second supply data are determined by the second energy subsystem on the basis of a system state of the second energy subsystem;
• calculating a divergence between a previously forecast system state for a time interval and a system state determined later for the same time interval;
• and
• at least one of the first supply data and the second supply data are determined so the divergence is minimized.

A method for controlling an exchange of energy in an energy system with multiple energy subsystems connected to one another for exchanging energy, the method comprising:

• receiving first supply data at a control center from a first energy subsystem, wherein the first supply data represent respective remuneration conditions of the first energy subsystem for receiving and/or providing energy;
• transmitting the first supply data to a second energy subsystem;
• receiving second supply data at the control center, the second supply data responsive to the first supply data, from the second energy subsystem, wherein the second supply data represent respective remuneration conditions of the second energy subsystem for receiving and/or providing energy;
• controlling an energy exchange between the first energy subsystem and the second energy subsystem based on both the first supply data and the second supply data;
• determining an amount of energy to be transferred during control of the exchange of energy between the first energy subsystem and the second energy subsystem;
• determining an amount of energy actually transferred after the exchange of electrical energy has been effected;
• and
• determining a measure of divergence that characterizes a divergence between the amount of energy to be transferred and the amount of energy actually transferred.
