Embodiment 1
[0094] Such as figure 1 As shown, the operation method based on VMD and OMP power load data dimensionality reduction algorithm is characterized in that: the method includes:
[0095] Step 1, collecting power load data;
[0096] Step 2. Perform data decomposition filtering and dimension reduction processing on the collected power load data through the variational mode decomposition method;
[0097] Step 3. After obtaining the natural mode components with frequencies ranging from low to high, the orthogonal matching tracking algorithm is used to reconstruct and optimize the decomposed and filtered data.
[0098] After the power load data to be tested is processed through the above three steps, complex, massive and high-dimensional data can be processed into simple, low-dimensional and easy-to-handle and analyze data; finally, in-depth research on the processed data, for Users, power companies and the government provide the basis for easy analysis of electricity consumption beh...
