Wind power plant wind speed prediction method considering coupling influence of low cloud and atmospheric boundary layer

The invention relates to a wind power plant wind speed prediction method considering low cloud and atmospheric boundary layer coupling influence. The method is suitable for the technical field of wind power plant wind speed prediction. According to the technical scheme, the wind power plant wind speed prediction method considering the coupling influence of the low cloud and the atmospheric boundary layer is characterized by comprising the steps of judging whether a cloud layer and the atmospheric boundary layer are in a coupling or decoupling state according to the relative position of the cloud layer and the atmospheric boundary layer; when the cloud layer and the atmospheric boundary layer are in a decoupling state, the turbulence exchange coefficient in the atmospheric boundary layer is determined based on a turbulence exchange coefficient driven by a ground buoyancy item; when the cloud layer and the atmospheric boundary layer are in a coupled state, the turbulence exchange coefficient in the atmospheric
