Zusammenfassung:The invention discloses a wind power generation power prediction method and system, and relates to the technical field of new energy power generation control. The method comprises the following steps: acquiring wind turbine generator information, wind regime information and terrain information; constructing a wind speed model based on a back propagation neural network and performing prediction to obtain a preliminary wind speed prediction result; determining coordinates and a relative position relation of the wind turbine generator according to the topographic information, and determining a wake flow superposition condition; correcting the initial wind speed prediction result and reconstructing a wind speed model; performing wind speed prediction by using the reconstructed wind speed model to obtain a final wind speed prediction result; and performing wind power generation power prediction through a wind power prediction model according to the final wind speed prediction result. The problem that wind power ge
