Abstract
The invention relates to a method for operating an electrolyser (2), comprising the following steps: (S100) inputting a value pair (Uact, Iact) indicative of a current electrical power (Pact) of the electrolyser (2); (S200) determining a compensation function (AGF) using at least the input value pair (Uact, Iact) and a further value pair (U0, I0); and (S300) determining an electrical power at the prediction point (Psp) using the determined compensation function (AGF).
