Method and system for detecting abnormal power consumption behavior of power consumer

Abstract

The invention discloses a method and a system for detecting abnormal power consumption behaviors of a power consumer. The method comprises the following steps: 1) obtaining user power consumption data through non-intrusive load monitoring; 2) processing the user power consumption data by adopting a deep Q network learning method to obtain a user power consumption behavior pattern pattern, wherein the user power consumption behavior pattern pattern comprises a checked abnormal user power consumption behavior pattern pattern; 3) extracting power consumption behavior characteristics from the checked abnormal user power consumption behavior pattern graph; 4) establishing a plurality of analysis models according to the extracted power utilization behavior characteristics; 5) adopting a Q network learning method to train and evaluate the plurality of analysis models, and selecting the analysis model with the optimal evaluation effect; and 6) detecting whether the power consumption behavior of the user is abnormal or not by adopting the analysis model with the optimal evaluation effect. Through monitoring and reasonable extraction and utilization of the electric energy data, reasonable power distribution of the power distribution network is facilitated, and the existing electric energy is used at the maximum efficiency.

Description

technical field [0001] The invention relates to the field of non-intrusive power distribution detection, in particular to a method and system for detecting abnormal power consumption behavior of power users. Background technique [0002] With the continuous improvement of informatization and digitalization, the era of big data has come. It has become an important task to dig out valuable information from massive and redundant data with low value, and extract common parts to form an effective mathematical model. Hot issues that all walks of life pay close attention to. For the power industry, with the continuous improvement of the informatization level of the power system and the rapid growth of the data volume of power distribution, various supporting devices and systems have a large amount of data to be processed, the data types are complicated, the data scale is huge, and the data content There is a lot of event information contained, but now we still face the important p...
