| Popis: | In this paper, we present a novel approach for the electricity theft detection (ETD). It comprises of two modules: (1) implementations of the six theft attacks for dealing with the data imbalanced issue and (2) a gated recurrent unit (GRU) to tackle the model’s poor performance in terms of high false positive rate (FPR) due to some non malicious reasons (i.e., drift). In order to balance the data, the synthetic theft attacks are applied on the smart grid corporation of China (SGCC) dataset. Subsequently, once the data is balanced, we pass the data to the GRU for ETD. As the GRU model stores and memorizes a huge sequence of the data by utilizing the balanced data, so it helps to detect the real thieves instead of anomaly due to drift. The proposed methodology uses electricity consumption (EC) data from SGCC dataset for solving ETD problem. The performance of the adopted GRU with respects to ETD accuracy is compared with the existing support vector machine (SVM) using various performance metrics. Simulation results show that SVM achieves 64.33% accuracy; whereas, the adopted GRU achieves 82.65% accuracy for efficient ETD. |
