Abstract

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