摘要

According to the characteristics of large-scale wind power cluster access, this article establishes an assessment method on flexibility demand of grid-connected wind farms based on correlation analysis. Firstly, considering that the meteorological conditions of adjacent new energy stations are similar, and the wind speed and solar intensity have strong correlation characteristics, the cluster correlation of new energy sources is analyzed. Then, based on the Copula theory, the analysis method of the nonlinear correlation of new energy output considering the effect of new energy cluster is studied, and the output of new energy cluster is modeled. Finally, based on the output model of the new energy cluster, the flexibility demand of large-scale grid-connected new energy is modeled, and the flexibility demand of power system is analyzed.
