  • Publication number: 20220108409
    Abstract: Various embodiments of the teachings herein include an energy system comprising: a central control unit; and an energy subsystem including an energy storage unit having a total storage capacity. The central control unit is programmed to control the energy storage unit based on an optimization. The total storage capacity of the energy storage unit is divided into a first partial storage capacity and a second partial storage capacity by the control unit for the optimization. The first partial storage capacity is designated for internal use with respect to the energy subsystem. The second partial storage capacity is designated for external use with respect to the energy subsystem.

  • Publication number: 20220069617
    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.

  • Publication number: 20220021219
    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.

  • Publication number: 20210390228
    Abstract: Various embodiments include a computer-aided method for simulating the operation of an energy system with a component comprising: modeling the energy system as an optimization problem with energy consumptions and energy outputs of the component and respective shadow prices associated with the energy consumptions and energy outputs as optimization variables; calculating the energy consumptions, the energy outputs, and the respective associated shadow prices by numerically solving the optimization problem; calculating a first sum of the energy consumptions weighted with the associated shadow prices; calculating a second sum of the energy outputs weighted with the associated shadow prices; calculating an incorrect dimensioning variable of the component by subtracting the second sum from the first sum, and using the investment costs and operating costs of the component; and determining overdimensioning or underdimensioning of the component as a function of the calculated incorrect dimensioning variable.
