Claim One:
1. A method for operating a wind power plant connected to a power grid, the wind power plant comprising a number of wind turbine generators, the method comprising: detecting one or more values of a plurality of power grid parameters; selecting a model from a plurality of different models, based on at least one of: the one or more detected values of the plurality of power grid parameters, one or more ambient parameter values, and an external command signal; wherein each of the models from the plurality of different models emulates an electrical behavior of an electrical system connected to the power grid; in the selected model, calculating electrical output values of the model, based on the detected grid parameter values; calculating electrical reference values for the wind power plant, based on the calculated electrical output values of the model; calculating electrical reference values for each wind turbine generator based on the calculated electrical reference values for the wind power plant; and controlling the wind turbine generators in the wind power plant based on the calculated electrical reference values for each wind turbine generator.
