Fault diagnostics in smart micro-grids: A survey

In this respect, this paper presents a review of different failure modes occurring in various micro-grid components including both clean and conventional energy generation systems. Subsequently, the paper also provides a review on the state-of-the-art of various fault diagnosis approaches available in technical literature. Since multiple approaches can be implemented utilizing the model-based or data-driven methods given the system monitoring and communication infrastructures, the paper has presented the material in a systematic manner for easy understanding. The information presented in this paper will benefit not only the diagnostic engineers but also the control engineers who aim to develop control methodologies for fault-tolerance, mitigation, and equipment life extension based on the tools of early diagnostics.
