Abstract

A method for controlling an electrical energy distribution network includes connecting at least one first distribution network of a first voltage level which comprises a plurality of network nodes to a power line of the at least one first distribution network, wherein a first part of the network nodes comprises energy consumers, a second part of the network nodes comprises energy generators, and a third part of the network nodes comprises both energy consumers and energy generators. A local unit of each of the network nodes records first energy quantity information which represents a measured energy quantity, and provides second energy quantity information which represents a tradable energy quantity. The method also includes transforming, by a device coupling the at least one first distribution network to a second distribution network, the first voltage level of the at least one first distribution network with a second voltage level of the second distribution network for an exchange of energy between the at least one first and second distribution network that is carried out, based on the first and second energy quantity information, between the network nodes within one of the at le…
