Portugal is seen worldwide as a case of success in the large-scale integration of renewables in its power system

especially for wind power. Consistent policies and sound management decisions are fundamental

but a sustainable process is not possible without the development of endogenous knowledge. This paper summarizes a set of models

both applied by the industry and representing actual technologic advancement

denoting the context of research and innovation in the country that helps to explain such success. Novelties arise in reliability assessment for systems with renewables

active and reactive power control

integration of wind farms

storage

electric vehicle integration

wind and solar power forecasting and distribution operation and state estimation taking advantage of smart grid structures. In all cases

one relevant trait is evident: the pervasive use of computational intelligence tools.
