摘要：The present invention relates to a method for providing fast and effective activepower support, such as inertial support, the method comprising the steps of determininga fundamental frequency of the power supply grid, changing a switching frequency of aDC/AC converter in case the determined fundamental frequency falls outside a
predetermined frequency dead-band of the power supply grid, and changing an amountof active power injected into the power supply grid in accordance with the changedswitching frequency in order to bring the fundamental frequency within the frequencydead-band of the power supply grid.
