Abstract :

Illegal Electricity Users Pose A Significant Threat To The Economic And Security Aspects Of The Power System By Illicitly Accessing Or Manipulating Electrical Resources. With The Widespread Adoption Of Advanced Metering Infrastructure (AMI), Researchers Have Turned To Leveraging Smart Meter Data For Electricity Theft Detection. However, Existing Models Rely On Methods That Model A Single Electricity Load Curve And Cannot Capture The Temporal Dependencies, Periodicity, And Underlying Features Between Electricity Consumption Cycles. This Study Introduces A Novel Electricity Theft Detection Method Based On Dynamic Residual Graph Networks. Innovatively, It Proposes A Dynamic Topological Graph Construction Technique That Allows For The Real-time Updating Of Adjacency Matrices During The Training Process, Thereby Effectively Capturing The Complex Relationships In Electricity Usage Patterns. Utilizing The MixHop Graph Convolutional Network, It Delves Into The Temporal Sequence Dependencies, Periodicity, And Hidden Characteristics Within User Electricity Consumption Data. Additionally, To Address The Issue Of Model Instability Caused By Scarce Theft Data, We Employ The SMOTE (Synthetic Minority Over-sampling Technique) Oversampling Technique And Enhance Overall Classification Performance By Modifying Class Weights In The Loss Function. We Trained This Network Architecture On The Real SGCC (State Grid Corporation Of China) Dataset, And The Results Demonstrate Its Superiority Over Other Mainstream Existing Models.
