“…The grid section including the distributed generation unit in islanding is referred to as a power island. Similar definitions can be found in the literature [7][8][9][10]. In principle, every self-commutated inverter is able to operate in islanding mode [11].…”

“…Similar definitions can be found in the literature. [4][5][6][7] Intentional islanding is possible without causing difficulties if the power island contains at least one generation unit that controls the voltage of the energized grid section. Examples are uninterruptible power supply systems where a power island is maintained intentionally in order to back up for a mains outage.…”

2Photovoltech SA, c/o IMEC vzw, B-3001 Leuven, Belgium Islanding is still one of the major controversial subjects in the international harmonization of grid connection requirements for distributed generation, and particularly photovoltaics. As long as islanding is not intended in order to back up a loss of mains, it should be avoided. The present study reviews the theory of unintentional islanding and assesses the probability of occurrence of the phenomenon, based on previous studies and theoretical considerations. While islanding is virtually impossible if only a small number of distributed generation units is connected to a distribution grid, with higher distributed generation densities, the possibility of islanding becomes realistic. The risk associated with unintentional islanding is estimated, and adequate requirements for functional safety of protection devices are determined in order to ensure the necessary additional degree of safety to be introduced by an islanding prevention device. Finally, a fundamental set of requirements with regard to islanding, to be included in an international grid connection guideline, is derived from the study.
