Evaluation index screening method and system for wind-solar-storage integrated operation system

The invention discloses an evaluation index screening method and system for a wind-solar storage integrated operation system, and belongs to the technical field of wind-solar storage system analysis. According to the method, firstly, dimension reduction is performed on indexes through a method of combining clustering analysis and AHP (analytic hierarchy process), clustering analysis is performed on the indexes preliminarily, the indexes with high correlation are clustered into one class, then the index with the maximum weight is screened out through an AHP method to serve as a representative index of the class of indexes, and finally, the indexes with the maximum weight serve as the representative index of the class of indexes. According to the method, the KMO coefficient is utilized to judge the overlapping degree among various representative indexes, and the indexes with overlapping performance are deleted according to the sampling adaptation quantity of each representative index, so that the information ov
