Embodiment Construction

[0052] This embodiment is further described in conjunction with the following embodiments.

[0053] In the smart grid, an intelligent control system is installed at each user end to collect the power consumption data of each household appliance that the user connects to the smart grid. The load identification method based on the power fingerprint classifies and identifies the user's household electrical appliance data. The result of the classification and identification provides a reference for the user to adjust power usage, or the identification result is uploaded to the power company as a reference for power consumption control on the supply side.

[0054] The load identification method based on power fingerprint, such as figure 1 As shown, firstly, the power fingerprint is extracted from the massive household appliance load electricity consumption data, and the "gradient boosting tree classifier" is used to mine the household appliance load power fingerprint to realize the...

Abstract

The invention relates to the field of intelligent power grid load identification technology application, in particular to a computer readable storage medium. A computer program is stored in the computer readable storage medium, and a load identification method based on power fingerprint is realized when the computer program is executed by a controller. According to the load identification method based on the electric power fingerprint, household appliance load identification features are extracted from massive household appliance load power utilization data through power calculation, Fourier analysis and other means, so that an electric power fingerprint set is obtained, training is performed through a gradient boosting tree classifier, and a gradient boosting tree classifier model is verified through a test data set; and finally, the trained gradient boosting tree classification model is used for household appliance load classification. And data mining is performed on the household appliance load electric power fingerprint by using the gradient boosting tree classifier so that rapid and accurate identification of the household appliance load of the intelligent power grid can be realized.

Description
