Problems solved by technology

[0005] The above methods all achieve load identification by extracting and transforming transient feature quantities, but because the entry point is relatively single, considering the uncertainty of transient features in the actual environment, the accuracy will be affected. Transient, steady-state Feature combination methods have also received attention

Abstract

The invention discloses a non-invasive electrical load identification method based on quantum genetic optimization. Specifically, the effective value of the current is obtained by using the measured load current and voltage data, and the optimal solution is obtained by comparing and optimizing through the quantum genetic algorithm, and finally determines the electrical load. specific load type. In the non-intrusive electrical appliance load identification method of the present invention, the quantum genetic algorithm is applied to the non-invasive electrical appliance identification technology on the genetically optimized electrical appliance identification algorithm, which increases the number of solution spaces for finding the optimal solution, and improves the identification results. The accuracy of multiple devices running at the same time also reduces the time complexity.

Description

Technical field[0001]The present invention relates to the field of non-invasive electric power load recognition, and in particular, to a non-invasive electrical load recognition method based on quantum genetically optimized.Background technique[0002]With the development of the smart grid, the proportion of resident users' electricity load in electricity load is increasing, as an important part of the power load, and the user domain load is increasingly concerned. Load online monitoring of residential domains is the basis for realizing electricity visualization of resident users. It helps users understand the specific energy consumption of electrical equipment in different times in the family. According to this, it is necessary to develop a reasonable power plan, improve energy consumption structure. Promote energy efficient use to reduce family electricity bills. The residential user domain load online monitoring plays an important role in promoting energy conservation and emission ...
