New sunshine-based models for predicting global solar radiation using PSO (particle swarm optimization) technique

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 25 March 2011brM.A., Behrang , E., Assareh , A.R., Noghrehabadi , A., GhanbarzadehbrPSO (particle swarm optimization) technique is applied to estimate monthly average daily GSR (global solar radiation) on horizontal surface for different regions of Iran. To achieve this, five new models were developed as well as six models were chosen from the literature. First, for each city, the empirical coefficients for all models were separately determined using PSO technique. The results indicate that new models which are presented in this study have better performance than existing models in the literature for 10 cities from 17 considered cities in this study. It is also shown that the empirical coefficients found for a…br Highlights: ► The first study to apply an intelligent optimization technique to more accurately determine empirical coefficients in solar radiation models. ► New models which are presented in this study have better performance than existing models. ► The empirical coefficients found for a given latitude can be generalized to estimate solar radiation in cities at similar latitude. ► A fair comparison between the performance of PSO and SRTs on GSR modeling.
