Abstract:Grid-connected wind farm is the chief way in wind energy development. The dynamic process of wind farm is far more complex than the conventional generator, such as hydraulic generator and coal-fired generator, for the wind farm is usually composed of many wind generators and the wind energy is strongly changeful. In simulation research, the wind farm is necessary to be equivalent to be one wind generator. In this paper, an optimization method for the parameters of the equivalent model based on the output characteristics of the wind farm is proposed. This method concurs the changeful characteristics of wind farm and the effect of the method is validated by the equivalence of a wind farm.
