A Grouping Method of Wind Turbine Generators Based on Fréchet Distance

Abstract

A large-scale wind farm usually consists of many wind turbine generators, and the model of such wind farm will be complicated if every wind turbine generator is modeled in detail. Therefore, an equivalent model is necessary to simplify the model and reduce the order of wind farm model. An appropriate grouping method is important for equivalent modeling. In this paper, a grouping method of wind turbine generators based on Fréchet distance is proposed, and the theory of this method is introduced. An example of wind farm is built and wind turbine generators in this wind farm are grouped by this method. The effectiveness of this method is confirmed by the output variables simulation curves of detailed model and equivalent model.
