Non-detection zones of an inverter based DER to islanding events and single-phase openings
2019 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America), 2019Distributed energy resources connected to distribution systems are vulnerable to islanding events and single-phase open. These two events have in common a circuit opening, and it is possible that single-phase opening events result in variations of frequency and voltage that cause protection actuation.

Modeling and design of phase shift anti-islanding method using non-detection zone
Solar Energy, 2007Abstract Islanding phenomenon of a grid-connected independent generator like a photovoltaic (PV) system occurs when a section of a utility system is disconnected from the main utility voltage source, but the independent generator continues to energize the utility lines in the isolated section. Since islanding causes a safety hazard to utility service

Positive feedback anti-islanding methods have been widely applied to inverter-based distributed generators recently due to their high cost-performance ratio. The effectiveness of these anti-islanding methods is usually demonstrated by means of steady-state non-detection zones (NDZs) represented in a load parameter space (LPS).

In this paper, the Non Detection Zones (NDZs) of frequency drift anti-islanding were compared according to the structure of positive feedback loop for closed-loop power controlled Distributed Generators (DGs). It was reported that the NDZ of frequency drift anti-islanding is enlarged with closed-loop based constant power controller.
