Abstract
A method of controlling a wind turbine having a generator system coupled to an electrolyzer for producing H2 from water is provided, the method including: identifying a characteristic of a load situation; operating the electrolyzer at a load and/or H2-output above a respective nominal rated value depending on the characteristic of a load situation; monitoring the state of the electrolyzer; and operating the electrolyzer at a load and/or H2-output not above the nominal value, if at least one state parameter is above a threshold.

A method of controlling a wind turbine having a generator system coupled to an electrolyzer for producing H2 from water, the method comprising:
- identifying a characteristic of a load situation;
- operating the electrolyzer at a load and/or H2-output above a respective nominal rated value depending on the characteristic of a load situation;
- monitoring the state of the electrolyzer;
- and
- operating the electrolyzer at a load and/or H2-output not above the nominal value, if at least one state parameter is above a threshold,
- wherein by operating the electrolyzer at a load and/or H2-output above the nominal value, at least one structural mechanical loading of a wind turbine component is reduced.
An arrangement of controlling a wind turbine having a generator system coupled to an electrolyzer for producing H2 from water, the arrangement comprising:
- a load identification module configured to identify a characteristic of a load situation;
- a control module configured to operate the electrolyzer at a load and/or H2-output above a respective nominal rated value depending on the characteristic of a load situation;
- a monitoring module configured to monitor the state of the electrolyzer;
- and
- wherein the control module is further configured to operate the electrolyzer at a load and/or H2-output not above the nominal value, if at least one state parameter is above a threshold,
- wherein by operating the electrolyzer at a load and/or H2-output above the nominal value, at least one structural mechanical loading of a wind turbine component is reduced.
