Abstract: An electrical energy distribution grid is controlled by a control center. Power target values for the real power and reactive power at a transfer point between the energy distribution grid and an electrical energy transport grid are prescribed by a target value device. The target values are to avoid backward feed into the energy transport grid that could lead to malfunctions. The real and reactive power target values are compared with current values at the transfer point. When a deviation of the actual values is determined, an optimization calculation is effected for the real power value and the reactive power value in the energy distribution grid to reduce or remove the deviation. The optimization generates switching commands for controllable operating devices, and a control device transmits the switching commands to the operating devices. There is also described a control center arrangement and a corresponding computer program product.

Abstract: Systems and methods for probability forecasts and an energy transmission and/or energy distribution network are provided. Operational management may be carried out using a network control system with systematic consideration of forecast uncertainties. The probability of a distribution network being operable in a stable manner (e.g., with N-1 certainty) in a planning period is included. The system includes a forecaster for forecasts for a planning period, a forecast analyzer connected to the forecasts from the at least one forecaster, and elements for further information for outputting estimated forecast uncertainties. The system also includes a stability probability analyzer connected to the forecasts from the at least one forecaster, the estimated forecast uncertainties from the forecast analyzer, and elements for further information for outputting at least one item of information relating to an N-1 stability of the distribution network in the planning period.

Abstract: Various embodiments include an island grid comprising: a power generator for generating an electric power; a controller for moderating an amount of electric power generated by the power generating unit; and a grid connection point to a superordinate electric grid. The controller operates the island grid in a first operating state decoupled from the electrical grid. The controller operates the island grid in a second operating state coupled to the electrical grid at the grid connection point. The control unit uses a separate controlled variable for each of the two operating states.

Abstract: An autonomous energy supply network has energy producers and energy consumers that are driven by a local control device. The following steps reduce the parameterization outlay required for the operation of the autonomous energy supply network: provision of model data of the autonomous energy supply network in a data memory of a computing device superordinate to the local control device, the model data specifying the respective energy producers and their operating parameters; determination of an operating plan for the autonomous energy supply network with the computing device by using the model data, the operating plan specifying the operating state of the autonomous energy supply network during a particular time interval; transmission of the operating plan to the local control device; and driving of the energy producers and/or the energy consumers according to the specifications of the operating plan by the local control device.

Abstract: A method for controlling an electrical energy distribution network in which electrical power is provided via network nodes connected via power lines is provided. A portion of the network nodes are controllable network nodes with respective local controllers, and at least a portion of the controllable network nodes are energy generators. The energy distribution network is coupled to an energy transmission network at a point of common coupling and provides electrical power to the energy transmission network at the point of common coupling. The electrical power originates from the controllable network nodes. A central controller communicates with the local controllers and the energy transmission network. The central controller controls the energy distribution network with the aid of the communication with the local controllers and the energy transmission network such that at the point of common coupling, primary control power and short-circuit power are kept available for the energy transmission network.
