Abstract: 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:

Abstract: 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.

Abstract: Various embodiments include a method for controlling load flows between multiple energy systems via an electrical grid using a control apparatus common to the energy systems. Each of the energy systems can provide a power associated with a load flow at a grid node. The method may include: ascertaining first powers scheduled for the load flows using data from the energy systems, including information about a maximum power providable at the respective grid node by the respective energy system; determining an internal controlling power to the electrical grid and resolved with respect to the grid nodes on the basis of the ascertained scheduled first powers and grid boundary conditions provided for the electrical grid; taking account of the controlling power determined at the grid node by reducing or increasing the maximum powers providable at that grid node by the energy systems; ascertaining scheduled second powers on the basis of the reduced or increased maximum providable powers; and controlling the load flows according to the ascertained second powers.
