Summary: The role of electricity theft detection is crucial in maintaining cost-efficiency in smart grids. Existing methods are limited by the large volume of data, missing values, and non-linearity. A novel framework is proposed that combines three modules to address these issues. The framework efficiently handles missing values, imbalanced datasets, and accurately predicts electricity theft cases using a hybrid classification approach and an improved artificial neural network.

Summary: In this article, simple data augmentation tricks (SDAT) are proposed to address the data imbalance issue in electricity theft detection. Five simple but powerful operations are introduced, including adding noises, drifting values, quantizing readings, adding fixed and changeable values. Numerical simulations on a real-world dataset demonstrate that SDAT can significantly improve the performance of different classifiers, particularly for small datasets. Specific suggestions on parameter selection for SDAT's transferability to other datasets are also provided.

Summary: This article analyzes the DC-link current ripple in switched reluctance machine (SRM) drive and proposes a control algorithm to reduce the ripple while maintaining machine performance. The proposed algorithm extracts ripple components from the DC-link current using a high-pass filter and ensures ripple energy circulation between phases, reducing the pulsating energy requirement from the DC supply. The DC-link ripple is suppressed at a wide speed range of operation to enable efficient and reliable drive operation without adding any external hardware system.
