Example Embodiment
[0078] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.
[0079] In this embodiment, the neural network model is built with Google's open source deep learning framework Tensorflow1.6 as the backend, Keras2.0 is the high-level API, the machine learning model is built as Scikit-Learn1.9, and the programming language is python3.6. This embodiment is initialized reasonably based on experience, and adjusted based on the training results.
[0080] Such as figure 1 As shown, the method of this embodiment is as follows.
[0081] Step 1: Collect data of wind power p and wind speed v, and perform preprocessing including: removing abnormal data, supplementing missing values, and normalizing to obtain the normalized wind power sequence X′ i ;
[0082] In this embodiment, actual opera...
