Daily global solar radiation prediction based on a hybrid Coral Reefs Optimization – Extreme Learning Machine approach.

Highlights: [•] This paper presents a hybrid CRO–ELM algorithm for solar radiation prediction. [•] Novel predictive meteorological variables are considered in this problem. [•] The CRO is a novel meta-heuristic search algorithm based on simulation of Coral Reefs. [•] The Extreme Learning Machine (ELM) is a state of the art method for training neural networks. [•] The proposed hybrid approach has shown excellent results in real data in Spain. [Copyright &y& Elsevier]
