1. A method 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 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;
verifying that the shadow flicker is generated by the at least one target wind turbine by comparing the flicker data and the operational data; and
pausing operation of the at least one target wind turbine verified to cause the shadow flicker.
