Summary

The rapid integration of renewable energy, distributed generation, and advanced power electronic devices is transforming modern power systems. While these developments enable cleaner and more resilient grids, they also introduce significant challenges to maintaining high power quality. Issues such as harmonics, voltage fluctuations, and missing or uncertain measurement data have become increasingly complex to address in this evolving environment. Novel monitoring, analysis, and control techniques are urgently needed to ensure the stable and reliable operation of next-generation grids.


This Special Issue aims to bring together cutting-edge research on methodologies and technologies that enhance power quality monitoring, diagnosis, and control. Particular emphasis is placed on artificial intelligence (AI)-based data processing, techniques for handling missing or corrupted data, and advanced diagnostic frameworks tailored to grid-forming and smart inverters. By bridging theory and practice, this issue seeks to highlight innovative approaches that ensure robust and sustainable power quality in modern energy systems.


Suggested themes include (but are not limited to):
- AI and machine learning for power quality monitoring and forecasting
- Missing data handling, data recovery, and uncertainty mitigation
- Grid-forming inverters, smart inverters, and novel converter technologies
- Advanced signal processing for harmonics and disturbances
- Cyber-physical approaches for resilient and adaptive power quality management

    Abstract To address the challenge of diagnosing stator single-phase ground faults in large fractional-slot hydro-generators, this study proposes an Improved Dung Beetle Optimizer (IDBO)-based Variational Mode Decomposition (VMD) method. Since VMD is highly sensitive to the selection of the number of modes K and the penalty factor α, improper parameter settings may result in incomplete signal decomposition and loss of fault-related features. To overcome this limitation, the conventional Dung Beetle Optimizer (DBO) is enhanced by incorporating a Logistic–Tent hybrid chaotic initialization, a dynamic convergence factor, and a random perturbation mechanism, enabling more accurate optimization of VMD parameters.
