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 comprises: setting up a number of different models, each model emulating an electrical behaviour of an electrical system, such as a load or a power generating unit, connected to the power grid; detecting one or more values of a number of power grid parameters; selecting one of the number of models, based on a number of values out of a set comprising the one or more detected power grid parameter values and one or more ambient parameter values, or based on an external command signal; 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; and calculating electrical reference values for each wind turbine generator based on the calculated electrical reference values for the wind power plant.
