Method for determining shadow flicker from a wind turbine system

A detector system to determine shadow flicker at a location in the vicinity of

• a wind park comprising a plurality of wind turbines;
• wherein the detector system, comprises:
• a remote detector configured to process data to generate flicker data representative of the shadow flicker at the location;
• and
• a wind power plant control system communicatively coupled to the remote sensor and configured to:
• identify at least one target wind turbine potentially causing a shadow at the location based on a position of the at least one target wind turbine and a position of the sun,
• generate operational data of the at least one target wind turbine, and
• verify that the shadow flicker is generated by the at least one target wind turbine by comparing the flicker data and the operational data.

A computer program product comprising software code adapted to control a wind turbine system when executed on a data processing system, the computer program product being adapted to perform an operation for determining shadow flicker caused by at least one wind turbine of a plurality of wind turbines, the operation comprising:

• determining a presence of shadow flicker at a location;
• generating flicker data representative of the shadow flicker;
• identifying at least one target wind turbine, of the plurality of wind turbines, potentially causing shadow flicker at the location based on a position of the at least one target wind turbine and a position of the sun;
• generating operational data from the at least one target wind turbine;
• and
• verifying that the shadow flicker is generated by the at least one target wind turbine by comparing the flicker data and the operational data.
