A method for controlling the distribution of electric power from a wind farm to a plurality of hydrogen producing electrolysers. The method includes estimating available DC power from the wind farm, which is controlled independently from the hydrogen producing electrolysers. A target current set point is determined for each electrolyser based on the estimated available DC power, the number of available electrolysers, and the voltage of each electrolyser. DC current supplied by at least one DC-DC power converter to each electrolyser is controlled to bring the DC current to the target current set point. The method is periodically repeated to compensate for changes in the DC power available from the wind farm.
