Abstract

The invention discloses a power signal adaptive reconstruction method in load decomposition, and the method can reconstruct a power signal sequence without missing data. The method comprises the following steps: acquiring the power signal sequence, and converting the power signal sequence into a power matrix; according to the power matrix obtained through conversion, constructing a transformationoperator matrix; constructing a measurement matrix; according to the obtained transformation operator matrix and the constructed measurement matrix, iteratively updating the power matrix, until the current iteration times is equal to length of the power signal sequence; and converting the currently obtained power matrix, and generating the power signal sequence without missing data. The method provided by the invention relates to the field of electric power.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power signal adaptive reconfiguration method in load decomposition. Background technique [0002] Load decomposition (also called: energy decomposition) is to decompose the power value read at the meter into the power value consumed by a single load, such as figure 1 As shown, among them, figure 1 The data in is simulated data, not measured data. [0003] 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. A...
