Zusammenfassung: | The invention discloses a typical scene generation method considering wind-solar power generation correlation. The typical scene generation method comprises the following steps: calculating a typical correlation coefficient reflecting original data correlation; generating a wind-solar power generation static scene, and obtaining a correlation coefficient; and selecting the typical coefficient to be matched with the correlation coefficient, finding out the output scene closest to the typical coefficient, and taking the output scene as a final typical scene set to reflect the correlation characteristics of the original wind and light power generation. According to the method, a Frank-Copula function is adopted to describe the correlation between wind power generation and photovoltaic power generation, Kendall rank correlation coefficients are selected as measurement indexes of correlation analysis of the wind power generation and the photovoltaic power generation, a K-means algorithm is used to cluster the corr |
