Substantial increase of wind energy production has made modeling of atmospheric boundary layer (ABL) flows over wind farms an inportant research topic. In the present work, Large Eddy Simulations (LES) are carried out to investigate the turbulent boundary layer flows over the two-dimensional RUSHIL wind-tunnel hill and the LES model is successively applied for the Bolund hill, which represents a real complex terrain. In order to validate our LES methodology presented here, the LES results are compared against the wind-tunnel and field measurements. It is shown that present LES results are in good agreement with the measurements in both cases. Furthermore, the LES methodology is utilized to simulate wind structures over the real wind-farm topography located in South-East Finland, and the preliminary results are reported in the this paper.
