A method for operating an electrical network comprising a first subnetwork and a second subnetwork that are connected to one another via a transformer and are DC isolated from one another by said transformer, wherein a primary side of the transformer having a first number of turns is assigned to the first subnetwork and a secondary side of the transformer having a second number of turns is assigned to the second subnetwork, wherein the first subnetwork has a multilevel converter having a plurality of single modules, wherein each single module has an electrical energy store, wherein the multilevel converter provides at least one first incoming AC voltage that is modulated with at least one second incoming AC voltage, wherein a voltage resulting therefrom is provided to the transformer and is transformed by the transformer to an outgoing voltage that is provided to the second subnetwork.
