Abstract

A method 200 for power oscillation damping in an AC power supply network by means of a connected electrolysis plant is presented, wherein the electrolysis plant comprises one or more electrolysis systems, each having at least a transformer unit, one or more rectifier units, and a set of electrolyser units connected to a DC side of the one or more rectifier units. The method 200 comprises measuring 202 a magnitude and an oscillation frequency of a power oscillation signal corresponding to an active power signal in the AC power supply network, and determining 203 the amplitude for oscillations with frequencies below the system's main frequency of the active power signal; and if said amplitude(s) is greater than a pre-defined threshold 204, changing 205 an operation mode of the electrolysis plant from a normal operation mode into a power oscillation damping mode and in said power oscillation damping mode, changing 206 an operation set point of a power consumption of the set of electrolyser units depending on a change of the magnitude of the active power signal.
