[0087] Below in conjunction with accompanying drawing, the present invention will be further described:
[0088] The present invention aims at problems such as low clustering accuracy and poor clustering effect due to the inability to provide local time frequency characteristics for nonlinear unsteady signals in the process of analyzing the characteristics of power users by traditional clustering algorithms, and proposes an experience-based An analysis method of power user characteristics combining modal decomposition and kmeans. The invention is applicable to any nonlinear and unsteady power grid load samples, expands data compatibility and improves clustering accuracy at the same time.
[0089] Based on BEMD and kmeans power user characteristic analysis method, the method includes:
[0090] Step 1. Obtain user power load data and store it as a database;
[0091] After a long period of accumulation, each power user in the power collection system has huge and complex load da...
