Abstract

The invention provides a wind power prediction method and system. The method comprises the following steps: obtaining meteorological data, received in a historical preset time range, of a preset place range; predicting special weather according to the received meteorological data, wherein the special weather comprises extreme weather; when the prediction result is the special weather, obtaining related influence data corresponding to the special weather; determining a correction factor of the measured wind field according to the historical operation data of the measured wind field corresponding to all special weathers before the prediction; and according to the influence data and the correction factor, determining an influence parameter of the special weather on the wind power generation power, and then according to the correction factor and the influence parameter, adjusting the wind power generation power of the fan predicted by using the existing wind power in the measured wind field. The wind power can be accurately predicted, so that a guarantee is provided for formulating a scheduling plan for a power system.

Description

technical field [0001] The present disclosure relates to the technical field of power prediction, and in particular to a method and system for wind power prediction. Background technique [0002] As the shortage of natural resources becomes more and more serious, wind power resources are widely concerned by the power industry due to their rich resources and renewability. However, as a power generation resource, wind energy has disadvantages such as instability, uncontrollability, randomness, and intermittency. Therefore, if the wind power can be accurately predicted, it can provide a guarantee for the power system to formulate a dispatch plan. . Contents of the invention [0003] One of the purposes of the present disclosure is to provide a wind power prediction method and system to realize accurate prediction of wind power, thereby providing guarantee for the power system to formulate a dispatch plan. [0004] In order to achieve the above object, according to the first...
