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.
