Problems solved by technology

[0004] At present, the research on the classification of power users lacks consideration of the characteristics of users in terms of power quality, and the data types used are single, and the relevant data information of users in terms of power quality cannot be extracted, which limits the application of power user classification in power quality of power grids.

Abstract

The invention relates to a power user grouping method and system based on the DTW distance and an affinity propagation clustering algorithm, and the method comprises the steps: collecting power quality monitoring data and user active power data, and constructing a feature matrix representing a time sequence change rule; calculating the feature similarity between each user and the power quality index, and quantifying the association degree of the user features and the power quality features; on the basis of the association degree of the user characteristics and the power quality characteristics, performing power quality characteristic similarity clustering calculation on different users, and classifying the users with similar association degrees into the same class; and providing corresponding electric energy with different electric energy qualities for users with different electric energy quality characteristics. According to the invention, user characteristic classification based on the aspect of power quality is realized, and a technical support is provided for lean power quality service of users.

Description

technical field [0001] The invention relates to the technical field of electric power system and electric energy monitoring, in particular to a power user grouping method and system based on DTW distance and neighbor propagation clustering algorithm. Background technique [0002] With the development of power technology and the improvement of users' requirements for power quality, power companies pay more attention to providing differentiated and personalized power quality services for power users. Improving the quality of power supply and consumption has become a prerequisite for ensuring the safe and stable operation of the power supply and demand system. . If the power sector only transmits power to users without considering its demand for power quality, poor-quality power will bring a series of safety hazards and social impacts. [0003] At present, there are problems in the power grid that data is not effectively connected, manual entry problems are common, and custome...
