Power system operation data modeling and feature selection method and device, electronic equipment and storage medium

Abstract

The invention belongs to the technical field of power system operation and control, and particularly relates to a power system operation data modeling and feature selection method and device, electronic equipment and a storage medium. The historical operation data preprocessing process and the original system physical simulation modeling are carried out; parallel simulation and batch data result labeling are performed on the modeled system; a first-stage feature selection and preliminary screening process of a filtering method based on a statistical method and feature association degree; and a second-stage feature selection fine screening process based on the rotating forest finally obtains a power system operation data feature subset with a small number of features, low feature redundancy and high feature key information density. According to the method, key features under an electric power system operation data framework can be extracted, and the accuracy and speed requirements of safety and stability analysis of the electric power system can be fully met. The method effectively improves the standard processing capability and the analysis and utilization efficiency of the operation data of the power system, and is easy to implement.

Description

technical field [0001] The present application belongs to the technical field of power system operation and control, and specifically relates to a power system operation data modeling and feature selection method, device, electronic equipment and storage medium. Background technique [0002] The scale of my country's UHV AC-DC hybrid power grid continues to expand, the extensive access of new energy sources and the increase in the degree of two-way interaction between flexible loads and the grid have increased the uncertainty of both sides of the source and load, and the characteristics of the grid have become increasingly complex. The operator monitors and regulates the safe and stable operation of the power grid, which poses a huge challenge. Therefore, it is of great significance to maintain the safe and stable operation of the power system to study the potential security and stability problems of the power grid, improve the observability and controllability of the power s...
