Abstract: A method for operating a control arrangement for an energy network. The control arrangement has a cloud infrastructure with data processor resources and data storage resources. A first group of software modules is executed on the cloud infrastructure, and a second group of software modules is locally executed on a server computer arrangement. The first group and the second group are connected for data communication via interfaces. The interfaces utilize a public key infrastructure (PKI) for encryption.

Abstract: A power transmission system has at least two local grids which are each connected to loads and are connected to a higher-level power transmission network. The power transmission system has at least one load control unit, each of which is connected directly or indirectly to at least one load of the at least two local grids and is suitable for controlling the consumption of the loads. The load control unit is suitable for evaluating the load state of the at least two local grids and, in the event of an overload which has occurred or is imminent on one of the at least two local grids, for reducing the consumption of at least one load of the local grid and conversely for increasing the consumption of at least one load in one of the other local grids, which is not overloaded, of the at least two local grids.

Abstract: A central device for a control system which controls an energy transfer system that has energy generators and energy consumers. The central device is suitable for determining, by an actual and/or a prognosticated energy consumption, how much energy should be generated by the energy generators. An individual energy bandwidth is assigned to at least one subgroup of the energy consumers connected to the energy transfer system, the bandwidth indicating to what extent the total energy consumption of the subgroup is expected to be able to be raised and/or lowered. The central device is suitable—in view of the energy generating behavior of the energy generators and the individual energy bandwidth of the subgroup—for determining an optimum target energy consumption which lies within the individual energy bandwidth and which the subgroup should achieve in total. The central device further generates a control signal indicating the target energy consumption.
