        abstract = {Phase locked loop and synchronization techniques are one of the most important issues for operating grid-interfaced converters in practical applications, which involve Distributed Power Generation Systems, Flexible AC Transmission Systems (FACTS), and High Voltage Direct Current (HVDC) Transmission, and so on.This paper proposes a systematic PLL modeling anddesign approach to evaluate different frequency-based islandingdetection methods. Two different types of PLL-based islandingdetection solution are discussed, accounting for a majority ofthe existing methods. The first method is to modify the PLL toconstantly move the stable equilibrium point. The second methodis to modify the PLL small-signal characteristics to achieve amonotonic instability behavior under the islanded conditions.The design procedures of these methods are presented using theproposed PLL modeling approach.},
