Abstract

The invention provides a short-term wind power prediction method and system based on a deep learning network. The short-term wind power prediction method comprises the steps of obtaining numerical weather forecast data of an area where to-be-predicted wind power is located; inputting the numerical weather forecast data into a pre-trained deep learning mapping model to obtain a predicted value of the wind power, wherein the deep learning mapping model comprises a corresponding relationship between the numerical weather forecast data and the wind power prediction value; and forming a grid by thenumerical weather forecast data according to positions, wherein each grid point in the grid comprises a plurality of weather parameters. According to the invention, the short-term power prediction precision of the wind power plant can be improved, meanwhile, the modeling time of the regional wind power prediction model can be shortened, and required computing resources and manpower resources arereduced.

Description

technical field [0001] The invention belongs to the technical field of clean energy consumption, and in particular relates to a short-term wind power prediction method and system based on a deep learning network. Background technique [0002] With the maturity of wind power generation technology, the capacity of wind power units and the scale of grid-connected wind farms continue to expand, and the proportion of wind power in the total power generation of the power system is also increasing year by year. The penetrating power of wind farms continues to increase, which brings a series of problems to the power system that are increasingly prominent, seriously threatening, and the power system is safe, stable, economical and reliable. Timely and accurate prediction of wind power can significantly enhance the safety, stability, economy and controllability of the power system, and enhance the ability to accommodate wind power. [0003] The existing short-term wind power forecast...
