MULTICHANNEL PRL: POWER GRID AND METHOD AND SYSTEM FOR PROVIDING A CONTROLLING POWER FOR REGULATING A POWER GRID FREQUENCY OF A POWER GRID

摘要

The present invention relates to a system and a method for providing control power for controlling a network frequency of a power network operated with a nominal frequency in the event of a frequency deviation of the network frequency from the nominal network frequency. A temporal course of the frequency deviation is spectrally split into at least two different spectral ranges, each of the spectral ranges being assigned to at least two different technical units for providing control power. The required control power is then provided individually or jointly by the technical units in accordance with the spectral split of the temporal course of the frequency deviation, wherein a respective power component of the technical units of control power corresponds to the spectral component of that spectral range, of the temporal course of the frequency deviation, that is assigned to the corresponding technical unit.
