Embodiment Construction

[0051] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0052] During the operation of the power system, extreme events such as short circuit of the power system and abnormal oscillation amplitude in the power system will occur. Extreme events will affect the stable operation of the power system and cause a lot of losses, so the prediction of extreme events is particularly important.

[0053] Therefore, there is an urgent need for a method that can predict the occurrence of extreme events so that preventive measures can be taken in advance.

[0054] In view of this, an embodiment of the present application provides a method fo...

Abstract

The present application relates to an extreme event prediction method, device, computer equipment, storage medium and computer program product. The method includes: obtaining historical electrical parameters of the power system in a first historical period; obtaining Gibbs measures of historical electrical parameters; inputting the Gibbs measures into a pre-trained event prediction model to obtain the output of the event prediction model Prediction information, the prediction information is used to indicate whether extreme events will occur in the power system at the target future moment after the first historical period; wherein, the event prediction model includes multiple neural network layers constructed based on the XGBoost algorithm and an extension for linking the neural network layers convolutional network. Using this method can realize the prediction of extreme events.

Description

technical field [0001] The present application relates to the field of power system technology, and in particular to an extreme event prediction method, device, computer equipment, storage medium and computer program product. Background technique [0002] During the operation of the power system, extreme events such as short circuit of the power system and abnormal oscillation amplitude in the power system will occur.
