1. A method for operating a wind farm having a first wind power installation and a second wind power installation, wherein the second wind power installation is located in a wake of the first wind power installation in at least one wake wind direction, the method comprising:
determining a tip-speed coefficient from a ratio of a second tip-speed ratio of the second wind power installation to a first tip-speed ratio of the first wind power installation,
determining a pitch-angle coefficient from a ratio of a second pitch angle of the second wind power installation to a first pitch angle of the first wind power installation,
determining a turbulence metric at the second wind power installation, and
operating the first wind power installation and the second wind power installation in a part-load range, wherein at least one coefficient chosen from the tip-speed coefficient and the pitch-angle coefficient is a function of the turbulence metric at the second wind power installation and is greater than one.
