Our proposed framework is synthesized from i) a dataset generated by introducing faults into an MG with PV cells, ii) processing the dataset to train various machine learning (ML) models for FD, iii) benchmarking the resulting FD models using classification metrics, and iv). . Our proposed framework is synthesized from i) a dataset generated by introducing faults into an MG with PV cells, ii) processing the dataset to train various machine learning (ML) models for FD, iii) benchmarking the resulting FD models using classification metrics, and iv). . Fault detection (FD) is crucial for a functioning microgrid (MG) but is particularly challenging since faults can stay undetected indefinitely. Hence, there is a need for real-time, accurate FD in the early phase of MG operations to mitigate small initial deviations from nominal conditions. The proposed solution uses a set of model-based and rules-based tec niques. . This paper proposes a distributed diagnosis scheme to detect and estimate actuator and power line faults in DC microgrids subject to unknown power loads and stochastic noise.
