Feeding electrical energy of distributed energy sources into an alternating current network

摘要

The method involves producing commands (11) of an inverter (5) at a central transfer point (4) for maintaining a reference value (15) of a physical parameter of supplied electric energy. The commands are wirelessly transmitted from the central point to the inverter when the electric energy supplied through a cable separation point to the transfer point is interrupted during non maintenance of the reference value. The reference value is changeable and variably preset by an operator of an alternating voltage network (2). An independent claim is also included for a device for maintaining a reference value of a physical parameter of electric energy comprising a processor device for generating commands of an inverter.
