Abstract: A method for modeling a network topology of a subarea of a low-voltage network, wherein the network topology of the subarea of the low-voltage network is dynamically changeable by switching on, over and/or off components and/or by adding or removing components, where the network topology is modeled as a graph with nodes and edges, states valid for all edges of the graph at an initialization time are determined and assigned to the edges as the respective first state instance, with each subsequent change to the network topology, the respective current states valid for the respective edge from a time of the change to the network topology are determined for the edges of the graph, and each edge of the graph is assigned the respective state determined and currently valid from the time of the respective change to the network topology as a respective further state instance together with a timestamp.

Abstract: A method for changing the configuration of at least two connected networks which consist of components and which are interconnected via at least one component, wherein at least one of the at least two networks is configured as a communication network, where digital models of the at least two networks are created based on network analyses, digital component models are created for the at least one connecting component, deriving a sequence of the configuration change is derived based on the digital models of the at least two networks and the digital component models for the at least one connecting component, the sequence of the configuration change is disassembled into decentrally executable sequence units and the decentrally executable sequence units distributing and executing while taking temporal and spatial dependencies on at least one decentralized sequence control unit in at least one of the at least two networks into account.
