Abstract

The invention relates to the technical field of power system planning, and discloses a wind power output prediction method, device and equipment and a storage medium, and the method comprises the steps: obtaining historical output data and basic data of a wind field; according to the basic data, utilizing a conversion model to convert the historical output data into historical wind speed data; based on the historical wind speed data, training a prediction model, and constructing the prediction model based on Weibull distribution of wind speed and a random difference equation; according to the trained prediction model, predicting predicted wind speed data in a future preset time based on a time sequence; and converting the predicted wind speed data into predicted output data according to the conversion model. According to the invention, the output condition in the future preset time can be accurately predicted.

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...
