Equivalent Modeling of Wind Farm Based on Fuzzy Clustering

摘要

Modeling of wind farm has become the focus research in the field of wind energy. In this paper, the wind generators are clustered through fuzzy clustering, every cluster contains certain number of generators. Each cluster can represent an equivalent generator; correspondingly the total power of wind farm will be the total power of all equivalent generators. This can avoid the gross error caused by taking the whole wind farm as one generator. The proposed method can largely reduce the computational complexity, which might lead to successful modeling of wind farm. The example simulation shows that the approach discussed in this paper can effectively indicate the power fluctuation of wind farm, and it is very helpful for wind power integration.
