Abstract

This application relates to the technical field of power system planning, and discloses a wind power output prediction method, device, equipment, and storage medium. The method includes: obtaining historical output data and basic data of the wind farm; The historical output data is converted into historical wind speed data; based on the historical wind speed data, the prediction model is trained, and the prediction model is constructed based on the Weibull distribution of wind speed and the stochastic difference equation; according to the trained prediction model, based on time series , to predict predicted wind speed data within a preset time in the future; according to the conversion model, convert the predicted wind speed data into predicted output data. The application realizes accurate forecasting of the output situation within a preset time in the future.

Description

technical field [0001] The present application relates to the technical field of power system planning, in particular to a wind power output forecasting method, device, equipment and storage medium. Background technique [0002] At present, in the simulation of existing wind farm processing, ultra-short-term wind power forecasting is often based on wind power forecasting methods, gray models and other forecasting models, which can only do ultra-short-term forecasting, and cannot take into account the distribution and timing of wind speed; And there is another type of ARIMA model based on time series, which considers the temporal characteristics of wind speed, but does not consider the distribution characteristics of wind speed. However, in the existing technology, there is no good method for predicting short-term or long-term wind field output. Therefore, how to complete the wind field output prediction on the basis of considering the distribution and time series of wind spe...
