Comparative Analysis of Some Remarkable Islanding Detection Techniques in Inverter-Based Distributed Generation Systems

Abstract

Recently, there is large scale of infiltration of renewable energy resources based distributed generation Systems (DGSs) into the power grid as cheap power can be available at local-end with less maintenance. However, islanding state of DGSs may enforces severe stability and security issues. Therefore, islanding condition in power system network need to be detected and addressed as soon as possible. For that an appropriate islanding detection technique is required. Vast research going on this topic and numerous techniques are found in literature till 2020 and some latest papers of 2021. New researchers need idea about available detection techniques. This paper may server for that purpose. Although some other significant review works on islanding detection technique are also available in literature in previous years but the necessary extensive analysis is also feature of this paper. Also, it includes some of the latest developed but distinct islanding detection techniques. In this paper, a thorough description and their classification of islanding detection techniques has been discussed. The classification structure has been built on control strategy, control variable types of circuitry, non-detection zone and weakness. This paper is intended to serve as a convenient reference for future researchers working on islanding issue for the DG power system.
