Wake Parametrization and surrogate modelling for loads prediction

Abstract

ln a wind farm, the wind velocity field hitting a rotor has some specificities. lndeed, when a wind turbine (WT) is located inside a warm, it experiences a modified wind field compared to the ambient one. Typically, inside a wake, the wind exhibits a reduced mean velocity and an increased turbulence intensity. The current design approach for wake induced load analysis just consists in using a kind of equivalent turbulence intensity that would cause the same damage as the wake induced wind field [1]. But this simplified approach does not account for the specific shape of the wake velocity field and may lead to inappropriate (conservative or under-conservative) load predictions especially for rotors operating in partial-wake conditions.
