 A microgrid is a portion of a distribution network and is commonly designed to operate in parallel with the power grid or autonomously as a power island. Therefore, islanding detection is one of the key aspects of grid connected microgrids.

 A microgrid is a portion of a distribution network and is commonly designed to operate in parallel with the power grid or autonomously as a power island. Therefore, islanding detection is one of the key aspects of grid connected microgrids.

In literature, performances of detection methods are largely tested with offline simulation tools and only very limited attempts are made with real-time hardware-in-the-loop simulations.

In this paper from IEEE, a detailed microgrid model is implemented in a digital real-time simulator to assess five different islanding detection schemes with practical synchrophasor measurements.

Performance of detection schemes are evaluated in terms of accuracy, speed of detection and non-detection zone, and quantitative results are presented.
