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.

Utilizing a mixed-methods approach, this research comprehensively evaluates socio-economic and technical factors that influence the adoption of DC microgrids. . In 2022, Indonesia allocated over USD 3 billion in expansion and renovation of its transmission and distribution systems, one-quarter less than the average in the previous 2017‑2021 period. The current investment level is expected to double to reach an average of USD 7 billion per year in 2030‑2035. . Indonesia is introducing technology to upgrade power grids. 2% in 2020, it has shown stagnating electrification since 2018. This is because most of the remaining areas that need to be electrified are remote and have unique characteristics that hamper implementation of microgrids for providing energy. .
