Computations of diffuse fraction of global irradiance: Part 2-Neural Networks

摘要

Solar energy is the feedstock for various applications of renewable energy systems, thus, the necessity of calculating and using global tilted irradiance is acknowledged for the computations of the performance and monitoring of Photovoltaic (PV) Parks and other solar energy applications. Thus, the aim of our research is to develop a model for the correlation of diffuse fraction (k(d)) and the clearness index (k(t)), that can then be used for the evaluation of the diffuse irradiance given the global irradiance.
