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 ...

Review of anti-islanding techniques in distributed generators
Renewable and Sustainable Energy Reviews, 2010 [EN] In this paper a revision about different techniques for islanding detection in distributed generators is presented. On one hand, remote techniques, not integrated in the distributed generators, are discussed. On the other hand, local techniques, integrated in the distributed generator, are described.

On active anti-islanding techniques: survey
Indonesian Journal of Electrical Engineering and Computer Science, 2021 The phenomenon of feeding loads from any distributed generators (DGs) with a total disconnection of utility grid at the point of common coupling is called Islanding. The DGs are usually independently controlled. Hence, when the islanding problem occurs, the electric utility loses the control and supervision over that section of the power grid ...
