Abstract:
The invention relates to a method for operating a converter in an energy distribution system, wherein, by means of the converter, an electrical energy provided by a source is fed into an AC electricity network at a coupling point (E) or electrical energy is drawn from the AC electricity network at the coupling point (E), wherein the AC electricity network is coupled to further converters for feeding in or drawing electrical energy, wherein the converter has an inverter provided with power switches in order to provide an electrical variable, comprising providing one or a plurality of system state variables indicating a system state of the electricity network, selecting one of a plurality of commutation patterns depending on the one or the plurality of system state variables, and driving the inverter according to the selected commutation pattern.
