A Comprehensive Review of Remote and Passive IDMs of Utility Grid Integrated MG System-Part Ⅰ

摘要

In this paper, different kinds of IDMs (remote, passive) have been described for the utility connected microgrid system. The IDMs comparison is made on the basis of standards of Table 1. Remote methods are based on the communication scheme, that is why cost is high and most reliable, as NDZ is zero and no power quality issue. But in case of local methods, these indices vary as per the different kinds of local methods named as passive, active and hybrid. Passive technique does not cause any problem on power quality and has high NDZ, but the modified or integrated passive has somehow less NDZ; i.e. why integrated passive IDMs are more beneficial. Generally, passive detection time is low compared to other methods. Due to the high cost and complexity during installation, RID methods are not chosen. After being the above-mentioned limitation of PID methods, still it is chosen over RID due to their lesser cost and easy implementation, but PID and modified PID are more suitable for the small microgrid system. For large system, RID is best. Hence, this literature is providing a good concept over islanding detection, and it will be helpful for the future research.
