Various embodiments of the present disclosure include a method for controlling one or more exchanges of energy between a plurality of installations using a control unit, wherein each installation is connected to one or more phases A,B,C of a three-phase power grid. An example method includes using the control unit to determine, within a time range T for each of the phases A,B,C and for each of the installations, associated time-dependent powers to be exchanged by means of an optimization method by extremalizing a target function. The target function includes a phase difference: as a term, where Pis in each case the sum of all powers to be exchanged via the respective phase A,B,C at the time t, and g≥0 is a weighting factor.

Controlling exchanges of energy between a plurality of systems connected to an electrical grid

Various embodiments include a control apparatus for controlling a power consumption and/or a power output of an energy system via a network connection point of a low-voltage network, wherein a line voltage can be detected at the network connection point by the control apparatus. The control apparatus comprises a processor programmed to reduce the power consumption and/or to increase the power output if the line voltage is below a first threshold value and/or to increase the power consumption and/or to reduce the power output if the line voltage is above a second threshold value greater than the first threshold value.

Control apparatus and method for controlling a power consumption and/or a power output of an energy system, and low-voltage network

Various embodiments include a method for certifying at least one installation-specific amount of energy, wherein the installation-specific amount of energy has been generated or consumed by an energy installation of an energy system. The method may include: capturing a temporal measured signal accumulated in relation to the energy system of a measured variable associated with the amount of energy; transmitting the captured signal to a test unit external to the energy system; disaggregating the transmitted signal using the test unit, and ascertaining the installation-specific amount of energy by way of the disaggregation; issuing a certificate regarding the ascertained installation-specific amount of energy; and receiving the issued certificate at the energy system.

Certification of at least one installation-specific amount of energy of an energy system

Various embodiments of the teachings herein include a device for controlling energy flows between components of an energy system with an energy accumulator comprising a controller for adjusting the energy flows. The controller computes the energy flows beforehand for a time domain using an optimization method, the time domain having a beginning and an end. A charge level of the energy accumulator at the end of the time domain is essentially equal to a charge level of the energy accumulator at the beginning of the time domain.

Device and method for controlling energy flows between components of an energy system

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.
