Abstract

The flow speedup generated by windbreaks can be used to increase the power production of wind turbines. However, due to the increased drag imposed by the windbreaks, their use in large wind turbine arrays has been questioned. We use large eddy simulations to show that windbreaks can increase the power production of large wind farms. A crucial finding is that windbreaks in a wind farm should be much lower than in the single-turbine case. In fact, the optimal windbreak for an isolated turbine can reduce wind-farm performance. The optimal windbreak height in a wind farm namely depends on the right balance between the flow speedup over the windbreak and the drag imposed by all windbreaks in the farm. The increased performance is a result of the favorable total pressure flux created by the windbreaks.
