[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0056] The present invention provides a kind of short-term wind speed prediction method based on improved whale algorithm optimization ELM, such as figure 1 As shown, it specifically includes the following steps:
[0057] Step 1: Obtain the time series of various meteorological data of the historical wind farm within the preset time range, preprocess the data and convert the processed data time series into matrix data, and divide the processed data into training set and test set.
[0058] Obtain data on various wind speed factors within a preset time range, including temperature, rainfall, wind direction, air density, and humidity. Preprocess the wind farm data to find out the mutation points in the actual wind speed in the training set, mainly including the points where the actual wind speed value is abnormally large and the actual wind speed value changes...
