Improvements in weather forecasting represent a great opportunity for wind power production. In order to make appropriate geographical choices of the areas to be exploited using this technology and to get an appropriate planning of power production, seasonal and subseasonal forecast is a research field where high gains can be obtained.
In the last twenty years, wind forecast has seen a lot of improvement for the short-term (1-7 days). However, this is only valuable for immediate energy production decisions. When it comes to medium-term planning of renewable production, it is necessary to go for a seasonal or subseasonal forecast.
However, the state of the art of the study of wind power planning at these scales is far from ideal. In this work, we analysed systematically the existing literature on the study of wind power for seasonal and subseasonal scale for the Iberian Peninsula and the Canary Islands (our region of interest given that Spain is one of the world leading producers of wind power) for the last ten years (2008-2018). The selected studies take into account only these regions or other biggest regions that include them. For our research, we used Google Scholar as search engine with four keywords optimized for our purposes.
The results showed that there are only a few studies that provide sensitive and useful information at the seasonal and subseasonal temporal scales for wind and wind power forecast for these regions. Finally, we discuss which are the major existing knowledge gaps and how research should evolve to improve the state of the art in wind power exploitation.
