Abstract: Various embodiments of the teachings herein include an energy management method for an energy system. The method may include: calculating a power prediction for use of an energy storage unit of the energy system for a time range; and determining, on the basis of the calculated power prediction, an externally usable partial storage capacity of the energy storage unit. The partial storage capacity according to the power prediction is not used by the energy system within the time range. The determined partial storage capacity is provided for use external to the energy system.

Abstract: Various embodiments of the teachings herein include a computer-assisted energy management method for an energy system, in which an operation of the energy system is regularly simulated according to a set call time interval for a set time horizon with a set time increment, comprising: determining whether a first parameter changes; performing an additional simulation of the operation of the energy system deviating from the set call interval based on the changed parameter; and/or within at least one critical time range in which a value of the first parameter is above a threshold value, performing a regular simulation which falls within the critical time range with a time increment which is smaller or greater than the set time increment; an operating the energy system according to either the additional simulation or the regular simulation.

Abstract: Various embodiments include a method for determining the thermal consumption of an energy system having a thermal energy storage unit, wherein the energy system generates a total thermal energy within a time range comprising: determining a thermal charging energy of the thermal energy storage unit within the time range; determining a thermal discharging energy of the thermal energy storage unit within the time range; and calculating a resulting thermal consumption within the time range using a sum of the total thermal energy and the difference between the ascertained thermal discharging energy and the ascertained thermal charging energy.

Abstract: Various embodiments of the teachings herein include methods for operating an energy management system of a grid participant electrically connectable to an electrical grid at a grid connection point comprising: a) receiving data from an electricity exchange characterizing a remuneration for a first service provided to the electrical grid by the grid participant and/or a second service obtained by the grid participant from the electrical grid; b) determining a load profile for the grid participant as a function of the received data, wherein the energy management system at least temporarily operates the grid participant according to the determined load profile so the grid participant provides the power to the electrical grid and/or obtains the power from the electrical grid; and c) transmitting the load profile to the electricity exchange.

Abstract: Various embodiments include a method for controlling an exchange of energy in an energy system with multiple energy subsystems connected to one another for exchanging energy comprising: receiving first supply data at a control center from a first subsystem, wherein the first supply data represent respective remuneration conditions of the first subsystem for receiving and/or providing energy; transmitting the first supply data to a second subsystem; receiving second supply data at the control center, the second supply data responsive to the first supply data, from the second subsystem, wherein the second supply data represent respective remuneration conditions of the second subsystem for receiving and/or providing energy, and controlling an energy exchange between the first subsystem and the second subsystem based on both the first supply data and the second supply data.

Abstract: The present invention relates to a fan module (10) that is comprised of a stationary fan element (1) and of a movable fan element (2) that has the ability to rotate. The fan module (10) has contact surfaces (5) on an outside lateral surface (4) that can be used to supply an operating voltage to an electric motor of the fan module (10). Consequently, a fan module (10) according to the invention can be quickly assembled and disassembled, allowing it to be replaced during continuing operation.
