4. Comparison with Existing Methodologies
- Based on the provided analyzes, the presented methodology detects islanding within 300 ms under various cases except for the small range of active power imbalance. Therefore, it can be considered among the fast and accurate existing IDMs.
- The thresholds of the local techniques rely heavily on the studied DG/system characteristics [4,5,6,7,9,10,11,12,13,14,15,16,17,18,19,20,22]. Therefore, a precise threshold(s) determination is mandatory for a new DG/network. Conversely, the settings of the proposed technique can be defined independently of the DG/grid characteristics (Equations (4)–(6)).
- In active and hybrid IDMs with periodic disturbance injection, the power quality is degraded, even in grid-tied operating mode. Whereas, the proposed algorithm exploits a short-duration disturbance under suspicious islanding events. Thus, the power quality remains almost unchanged during grid-connected situations.
- The total cost of the proposed technique includes the measurement of the output current, voltage, active power estimation, and a pre-defined disturbance injection into Id,ref. Hence, the investment for sensors, microcontroller/digital signal processor, and a signal generator is estimated lower than 100 USD. By contrast, the realization of the remote techniques is costly, especially for small-scale microgrids [24,25,26].
