One of the most important parameters of the system where wind turbine generators (WTGs) are connected is voltage profile at the point of common coupling (PCC). In the earlier stage, WTGs were possible to be disconnected from the system to avoid the damage of WTGs. Following the rapid injection of WTGs to the existing network during last decades, the transmission line operators (TSOs) require WT...

With the continuously increasing penetration of networked microgrids (MGs) on local utility grid (UG), MGs face challenge to avoid system fault currents during low-voltage ride-through (LVRT). To solve this challenge, an active current limitation (AFCL) method is proposed with three parts: 1) a novel phase angle adjustment (PAA) strategy conducted relieve impact output current; 2) injection (CI...

A novel control strategy is proposed in this paper for the rotor side converter (RSC) of doubly-fed induction generator (DFIG)-based wind power generation systems. It is supposed to enhance the low-voltage ride-through (LVRT) capability of DFIGs during great-level grid voltage dips. The strategy consists of a proportional-resonant (PR) controller and auxiliary PR controllers. The auxiliary cont...
