Power prediction model establishing method and device, power prediction method and device, and electronic equipment

Abstract

The embodiment of the invention provides a power prediction model establishing method and device, a power prediction method and device, and electronic equipment. The establishing method of the power prediction model comprises the following steps: obtaining sample prediction wind speed data and sample actual measurement wind speed data corresponding to the sample prediction wind speed data; dispersing the sample prediction wind speed data into a plurality of wind speed segments according to a preset wind speed value interval; determining the predicted power of each wind speed segment according to the accuracy relationship between the predicted power and the actually measured power; and determining a power prediction model according to the prediction power of all the wind speed segments. The power prediction model constructed by the method for establishing the power prediction model provided by the embodiment of the invention can effectively improve the power prediction accuracy, is suitable for both ultra-short-term prediction and short-term prediction, and is closer to reality in obtained prediction result due to the fact that the sample is utilized to predict the wind speed data.

Description

technical field [0001] The present application relates to the technical field of wind power, and in particular, the present application relates to a method for establishing a power prediction model, a prediction method, a device, and electronic equipment. Background technique [0002] Power prediction establishes a prediction model of the output power of the electric field based on the historical power and historical wind speed of the wind farm, and takes wind speed, power or numerical weather forecast data as the sample data input for model training to obtain the predicted output power for the electric field. Power forecasting is divided into short-term forecasting and ultra-short-term forecasting according to the forecast duration. Short-term forecasting refers to predicting the output power of wind power within 1-3 days in the future, while ultra-short-term forecasting refers to predicting the output of wind power within 0h-4h (hours) in the future. power.
