Synchronization instability of grid-tied converters during grid faults is a serious concern. For phase-locked loop (PLL) synchronized converters, synchronization stability during grid faults requires that PLL can resynchronize with the power grid. It is of great significance for meeting grid code specifications such as reactive current support. However, the synchronization in the context of high-impedance weak grid is not always readily achieved. On one hand, the terminal voltage of converters… 

Synchronization Instability of Inverter-Based Generation During Asymmetrical Grid Faults

An adaptive PLL that switches between the second-order and the first-order PLL during the fault-occurring/-clearing transient is proposed for preserving both the transient stability and the phase-tracking accuracy.

Resynchronization Analysis and Improvement of Grid-Connected VSCs During Grid Faults

A variable structure PLL method with great simplicity is proposed to improve the resynchronization capability of VSCs during grid faults by removing PLL’s integral regulator, which causes the system operating point to enter negative damping zones and even reverse regulation zones, resulting in LOS.
