Table 5 Comparison of IDMs
From: Shifting of research trends in islanding detection method - a comprehensive survey
IDM | Basic principle | NDZ | Run on time | Nuisance tripping percentage | Applicability in multiple DG system | Implementation cost | Effect on microgrid |
|---|---|---|---|---|---|---|---|
Active | Injecting disturbance and analyzing the impacts | Small | Short | Low | Not preferred | Low | Highly degrades the power quality |
Passive | Monitoring system parameters | Large | Very Short | High | Highly preferred | Low | None |
Hybrid | Combination of active and passive | Very small | Short | Low | Not preferred | Low | Degrades the power quality |
Local | Communication between DG | Zero | High | Negligible | Preferred | Extremely High | None |
Signal processing | Extraction of features by signal processing tools | Negligible | Short | Low | Preferred | Low | None |
Classifier | Classification based on input features | Negligible | Short | Very low | Preferred | Low | None |
