Taxonomy on DSP Based Islanding Detection Techniques in Micro Grid

Abstract

The DG paradigm, which combines renewable and non-renewable energy resources to create a Micro grid that can be run more safely and effectively using fast islanding detection methods, is being adopted by the majority of sophisticated power system networks. Several islanding detection methods like Conventional passive detection methods having large Non detection zone (NDZ) with irregular threshold settings. The active detection techniques having intentional perturbation causing major disadvantage in improved rapid operation of Microgrid. In this concern with improved efficiency, accuracy, and reliability have been proposed in the literature. Signal Processing (SP) based passive Islanding detection Techniques are extensively analyzed by proper comparison under various aspects which is feasible and economical and can avoid the above said drawbacks for stable operations. This paper’s major contribution is to provides operation of islanding detection technique for voltage and current signals generated at point of common coupling with DSP based method which can compare the detection time which is the part of various Transformation techniques which has approached.
