Study and Comparison of Wind Power Correlation Using Two Types of Dataset

With the integration of large-scale wind farms, stability and economy of power grid are greatly challenged. Considering the stochastic characteristics of wind and the coupling relationship of geographically distributed wind farms, this paper presents the comparison of analysis methods and results when using wind speed dataset and wind power output dataset in wind power spatial correlation research based on copula. Combined with several revised criteria, a novel method is proposed to select copula type and judge goodness of fit. In the case study, copula models and typical scenarios using the two datasets are highlighted and compared. Study results clarified the advantages and disadvantages of using different datasets.
