A load management system for managing loads in a power distribution grid. The load management system includes a control unit and at least two current transformers, which are each connected to the control unit by a signal cable. A first current transformer of the at least two current transformers is arranged in the power distribution grid such that the first current transformer is suitable for measuring a current level that is dominant in a grid connecting line of the power distribution grid, which grid connecting line is connected to a power supply company. A second current transformer of the at least two current transformers is arranged in the power distribution grid such that the second current transformer is suitable for measuring the current level that is dominant in a power line of the power distribution grid, which power line feeds at least one charging station of the power distribution grid.

Load management system and method for managing loads in a power distribution grid

A method and an apparatus for energy management including an input for a first sensor, which is designed to detect a first measurement variable as information about a current to a home energy management system. A device is designed to determine a second measurement variable depending on the first measurement variable. An output designed to output the second measurement variable, instead of the first measurement variable, as information about a current to the home energy management system for the home energy management system.

Method and apparatus for energy management for an electric vehicle charging system

A method for controlling a supply of at least one load with voltage and/or electric current through an electric network.

Method and device for managing an electricity supply through an electric network and for controlling an electrical supply to a consumer of electricity

A method for distributing energy in the home energy management system including a central unit, an energy source, and an energy consumer. The central unit, the energy source, and the energy consumer are connected for exchanging information items. The central unit generates an information item which contains a first price information item and a first amount-of-energy information item for a predetermined period of time. The central unit transmits the information item to the energy consumer. The energy consumer ascertains a requirement information item taking into account the information item. The requirement information item contains a requested amount of energy for the predetermined period of time. The energy consumer transmits the requirement information item and a second price information item to the central unit. The central unit checks whether the overall requested amount of energy ascertained from the transmitted requirement information items at any one time exceeds the amount of energy available at this time. The central unit transmits the acknowledgment information item to the energy consumer.

Method for distributing energy in a home energy management system

A method for distributing energy in a home energy management system including a central unit, at least one energy source and at least one energy consumer that are interconnected to exchange information. According to the method, the central unit generates information containing a first price information element and a first energy quantity information element for a predefined time period; the central unit transfers the information to the energy consumer; the energy consumer, taking account of the information, determines requirement information containing at least one requested energy quantity for the predefined time period; the energy consumer transfers the requirement information to the central unit; the central unit checks whether, at any given time, the total requested energy quantity determined from the transferred requirement information exceeds the energy quantity available at this time; and the central unit transfers confirmation information to the energy consumer or the method is carried out again.
