Research on solar beam-diffuse radiation separated model based on BP neural network

Abstract

Trying to PM<sub>2</sub>.s as the independent variable to establish the “beam-diffuse radiation separated” model, factor analysis showed that, PM<sub>2</sub>.<sub>5</sub> and diffuse ratio have positive correlation. Based on the clearness index K<sub>t</sub> and sunshine hours n/N as variables, the polynomial model and the BP neural network algorithm model… (More)
