ABSTRACT: Islanding detection is an essential function for safety
and reliability in grid-connected Distributed Generation Systems (DGS).
Passive and active islanding detection methods have been analyzed in literature
considering DGS with only one inverter connected to the utility. With the big
scale application of photovoltaic (PV) power systems, islanding detection
technology of multi-inverter DGS has been paid more attention. This paper
analyzes the performance of diverse islanding detection methods in multiple
inverters grid-connected PV systems. Non-Detection Zones (NDZ) of
multi-inverter systems in a load parameter space are used as analytical tool.
The paper provides guidance for the islanding detection design in multiple
grid-connected inverters.
