  • Publication number: 20240362727
    Abstract: Systems, methods, and apparatuses are provided for operating an energy market platform for an energy trade for at least one aggregator using an electronic computing device. A time period is specified for the energy trade is subdivided into a multiplicity of time units. A respective energy potential is determined for each of the time units according to at least one energy system. The respective energy potential is represented so as to be visible to the aggregator on the energy market platform. A time-unit-dependent trade energy request is compared with the corresponding energy potential using an input by the aggregator. A multiplicity of at least partially electrically operated motor vehicles is provided. Using the energy market platform, the respective energy is determined such that, at a specific time point, a respective at least partially electrically operated motor vehicle assumes a specific energy volume.
