Abstract

The invention discloses a power signal noise filtering method and system for energy decomposition, and the method employs the step characteristic and sparsity of the amplitude of a power signal, employs similar signals to estimate adjacent signals, and achieves the purpose of noise filtering. The noise filtering method provided by the invention has relatively good robustness and a noise filteringeffect, and the step characteristic of the power signal can be well kept, so that the noise filtering method can be further used for energy decomposition, and the filtering process is simple to calculate.

Description

technical field [0001] The invention relates to the technical field of power signal filtering, in particular to a power signal noise filtering method and system for energy decomposition. Background technique [0002] With the development of smart grid, the analysis of household electricity load becomes more and more important. Through the analysis of electricity load, household users can obtain the electricity consumption information of each electrical appliance in a timely manner, as well as a detailed list of electricity charges; the power department can obtain more detailed user electricity consumption information, and can improve the accuracy of electricity load forecasting, Provide a basis for overall planning for the power sector. At the same time, using the electricity consumption information of each appliance, the user's electricity consumption behavior can be known, which is of guiding significance for household energy consumption assessment and research on energy-...
