Abstract
A method is proposed for operating at least one wind turbine of a wind farm including determining wind turbine individual offset information based on reactive power provided by the respective wind turbine and reactive power provided by at least one further wind turbine of the wind farm, determining wind turbine individual control information based on the wind turbine individual offset information and wind farm specific control information, operating the at least one wind turbine according to the wind turbine individual control information. Further, a controller and a device as well as a computer program product and a computer readable medium are also provided.

A method for operating at least one wind turbine of a wind farm, comprising the following steps:
- determining wind turbine individual offset information based on:
- reactive power provided by the respective wind turbine, and
- reactive power provided by at least one further wind turbine of the wind farm;
- wherein the wind turbine individual offset is based on a deviation information that is provided to an input of a processing unit comprising an amplifier and a limiter;
- determining wind turbine individual control information based on:
- the wind turbine individual offset information and
- wind farm specific control information;
- and
- operating the at least one wind turbine according to the wind turbine individual control information.
A controller for operating at least one wind turbine of a wind farm, comprising:
- a processing unit comprising an amplifier and a limiter that is arranged for:
- determining wind turbine individual offset information based on
- reactive power provided by the respective wind turbine, and
- reactive power provided by at least one further wind turbine of the wind farm;
- determining wind turbine individual control information based on:
- the wind turbine individual offset information and
- wind farm specific control information;
- and
- operating the at least one wind turbine according to the wind turbine individual control information.
A method for operating at least one wind turbine of a wind farm, comprising the following steps:
- receiving a reactive power value for the respective wind turbine and at least one further wind turbine of the wind farm;
- calculating a mean of the reactive power values for the respective wind turbine and the at least one further wind turbine of the wind farm;
- determining wind turbine individual offset information based on the reactive power value provided by the respective wind turbine and the mean of the reactive power values for the respective wind turbine and the at least one further wind turbine of the wind farm,
- wherein the wind turbine individual offset information is based on deviation information representing a deviation or difference between the reactive power provided by the wind turbine and the mean value of reactive power values for the respective wind turbine and the at least one further wind turbine of the wind farm,
- further wherein the deviation information is processed based on at least one of the following functionalities:
- applying a gain factor,
- applying an integration, and
- applying a limiting factor;
- determining wind turbine individual control information based on the wind turbine individual offset information and wind farm specific control information;
- and
- operating the at least one wind turbine according to the wind turbine individual control information.
