This chapter is devoted to markovian approaches to model first the wind speed in a given site starting from experimental results and, then, power availability of a wind turbine installed in assigned wind conditions. The chapter organization is as follows: section 2 is devoted to wind data and their treatment; section 3 presents two wind models with different accuracy; section 4 describes produced power models for wind turbines, first in hypotheses of ideal failure-free turbine and, then, accounting for a real behaviour; section 5 is devoted to model analytical solutions; section 6 reports the results of numerical examples developed for a very simple case-study; section 7 describes some possible model applications; section 8 concludes the chapter; section 9 is constituted of an appendix on the basic Markov model concepts. A significant part of the chapter content derives from references (Manco & Testa, 2007 and to other references of the chapters’ authors reported in Section 10).
