Over/Undervoltage and Undervoltage Shift of Hybrid Islanding Detection Method of Distributed Generation [PDF]
The Scientific World Journal, 2015 The mainly used local islanding detection methods may be classified as active and passive methods. Passive methods do not perturb the system but they have larger nondetection zones, whereas active methods have smaller nondetection zones but they perturb ...

International Journal of Integrated Engineering, 2019 Renewable power generation systems have more advantages in the integrated power system compared to the generation due to fossil fuels because of their advantages like reliability and power quality. One of the important problems due to such renewable distributed generation (DG) system is an unintentional islanding.

A passive islanding detection strategy for multi-distributed generations
International Journal of Electrical Power and Energy Systems, 2018 Abstract Islanding operation is an undesirable event because it can harm the personnel and damage the connected loads. Therefore, islanding operation should be detected and the islanded distributed generation units should be isolated from the rest of the distribution network.
