Abstract In distributed generation (DG) systems, the rate of change of voltage and the rate of change of frequency are the two most common and widely used simple and low-cost passive islanding detection schemes. Unfortunately, these passive islanding detection schemes find limitation for detecting the islandings that cause very small power imbalance. In this paper, an improved passive islanding detection scheme is proposed by using the two newly derived indices from the sequence components of the current signal with the conventional voltage and frequency parameters. The performance of the proposed scheme is tested for numerous islanding and non-islanding cases generated on IEEE Std 399–1997 and IEC microgrid model distribution system integrated with both inverter-interfaced and synchronous DGs through PSCAD/EMTDC. The obtained results confirm the effectiveness of the proposed scheme.

Renewable energy is substantially applied at the distribution grid in order to fulfill the electricity demand as well as addressing global heating issue caused by conventional energy source. However, application of the distributed energy source raises new concern in regards of unintentional islanding activity in which prompts grid protection issues hence, endangering utility worker’s safety. These several decades feature thousands of invention and innovation of anti-islanding method developed by researchers to satisfy the demand of grid protection. Therefore, this paper conducts an overview on several islanding detection schemes with concentration on the mechanism of the method, the merits as well as the demerits of the scheme. It is concluded that there is no ideal method developed as yet, but some of these methods or integration of them are able to be applied practically to specific distributed source and grid structure.
