One of the crucial problems for wind farm development is wind farm layout optimization. It seeks the optimal positions of wind turbines inside a wind farm, so as to maximize and/or minimize a single objective or multiple objectives, while satisfying certain constraints. Although this problem for wind farms in flat terrain or offshore has been investigated in many studies, it is still a challenging problem for wind farms in complex terrain. Designing wind farms in complex terrain is becoming more and more important...

In this study, the depth-averaged flow equations for wind farm simulation on the complex terrain are presented. The equations are derived by integrating the original 3D flow equations over the height of the channel depth. This approach reduces the equations from 3D to 2D and reduces the elapsed time of CFD simulations from hours to minutes. Thus, it is very practicable modelling method in real time design work. 2D CFD simulations with depth-averaged equations are compared with full 3D models for the Lillgrund wind...
