Abstract: A network (1) for distributing electrical energy comprises a first network area (10) consisting of a plurality of local, self-regulating functional groups (11.1 . . . 8) having first sources, loads, lines and/or sensor, switching or converter components, wherein each of the functional groups (11.1 . . . 8) is designed for complying with assigned regulation limits for voltage quality variables in the network (1), and wherein the first network area (10) has a first size, and a second network area (20) having second sources, loads, lines and/or sensor, switching or converter components, wherein an estimated total variance of the voltage quality variables is assigned to the second network area (20), and wherein the second network area (20) has a second size. The regulation limits of the functional groups (11.1 . . . 8) and the first size are chosen such that, taking account of the second size and the estimated total variance, predefined target operating range limits for the entire network (1) are complied with.

Abstract: In a method for structuring an existing grid (11) for distributing electric energy, wherein the grid (11) comprises, as grid components, at least sources, loads, lines, sensor, switching and converter components which are connected to one another in a starting topology, on the basis of property variables of the grid components and predefinable regulation limits, the grid components are combined in a plurality of local, self-regulating functional groups (30.1, 30.2, 30.3). Each local functional group (30.1, 30.2, 30.3) is assigned regulation processes comprising actions which are carried out upon reaching trigger criteria for complying with the regulation limits. Starting from an existing grid for distributing electric energy, the method results in a grid which is newly structured in terms of the regulation and, as far as possible, dispenses with a hierarchical structure with respect to the regulation and instead is constructed from local functional groups (30.1, 30.2, 30.
