Energy distribution system and method for operating same

Abstract

In an energy distribution system, energy is fed through substations into subnetworks and the distribution is monitored by a central device superordinate to the substations. At least one substation is operated in an optimization mode for optimizing the operation of the entire energy distribution grid. The substation thereby investigates a modification action which could be performed by the substation in its subnetwork for the effect of the modification action on the operating state of the entire energy distribution system. The substation receives substation-individual sensitivity values, which indicate the change in the local operating state in the subnetwork assigned to the respective other substation if the modification action were to be implemented. The substation operated in the optimization mode checks, based on the sensitivity values, whether the modification action would result in an improvement of the operating state for the entire energy distribution grid.
