proposition for small-scale insular grids, Renew. Sustain. Energy Rev. 27 (2013) 65e76.
Fig. 3.9 summarizes the best uses of the main existing methods (time seriese
based methods, NWP-based methods, satellite- and image-based methods) accord-
ing to the forecasting time horizon and the temporal resolution.
The existing methods can be classified in four different categories [30]:
(Fig. 3.10):
