Design-Oriented Transient Stability Analysis of PLL-Synchronized Voltage-Source Converters [PDF]
IEEE transactions on power electronics, 2018 Differing from synchronous generators, there are lack of physical laws governing the synchronization dynamics of voltage-source converters (VSCs). The widely used phase-locked loop (PLL) plays a critical role in maintaining the synchronism of current ...
