当与在与风电场相同的风输入条件下操作的相同数量的广泛分散的涡轮机相比时，在风电场中分组在一起的涡轮机之间的空气动力学相互作用导致从风中提取的总能量的减少。寻轨控制（ESC）是一种有望在某些风力输入条件下减少这种影响的策略。在本文中，我们评估了ESC在不同湍流条件下的有效性，描述了解决涡轮机之间的湍流风输入和随时间变化的风延迟所造成的复杂性的方法，其中这两个元素是与其他风电场控制研究相比最重要的贡献。结果表明，在低湍流强度条件下，能量捕获可以增加，但在高湍流强度条件下可能不会。
Aerodynamic interaction among turbines grouped together in wind farms causes a decrease in the total energy extracted from the wind when compared to an equal number of widely dispersed turbines operating under the same wind input conditions as the wind farm. Extremum seeking control (ESC) is one strategy that holds promise for reducing this impact under certain wind input conditions. In this paper, we evaluate the effectiveness of ESC under different turbulence conditions, describing methods for addressing the complexities caused by the turbulent wind input and time-varying delay of the wind between turbines, where these two elements are the most important contributions compared to other wind farm control research. The results show that energy capture can be increased in low turbulence intensity conditions, but perhaps not in high turbulence conditions.
