To make up for the defects existing in the tradi- tional single clustering methods, this paper creatively combines classical ART2wNF neural network clustering algorithm with K-means algorithm and form a new "double standard, double clustering" comprehensive clustering method. It incorporates Ashland photovoltaic power station (5 kW) measured data of 2001 to get detailed instructions on how the data according to the procedures followed in the K-means algorithm and the ART2wNF neural network to complete clustering, draw out the clustering res...
