Comparative Analysis to Emphasize on Islanding Detection Techniques in Integrated Distributed Generation System

Abstract

Grid fusion of renewable energy based distributed generation (DG) is gaining popularity globally due to their benefits of increasing efficiency, power quality, and system reliability. In front of their benefits, they are enduring the issues of unintentional islanding. Islanding is caused in the distributed generation because of system faults and equipment failure in the main grid. So, the islanding must be detected within 2s as recommended by distributed generation interconnection standards. Islanding identification in the micro grid is an essential key constraint for evolving safety and competent functioning of a power system. This paper presents a quick summary of various islanding detection methods in Integrated distributed generation systems. This work has concluded with few gaps existing in islanding detection techniques with their benefits and drawbacks.
