  "textContent": "A method of operating a wind turbine during disconnection from a utility grid includes a generator, a wind turbine converter, in particular including a grid side converter portion connectable to the utility grid, a DC link, a generator side converter portion, and a UPS, the method including: allowing the UPS to draw, according to an UPS active power reference, active power from the wind turbine converter (); controlling the wind turbine converter by a converter power reference to meet the UPS active power reference. Controlling the wind turbine converter by the converter power reference includes modulating a frequency of the converter terminal voltage in dependence of the converter power operating point, in particular the converter power reference.",
