Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters [PDF]
, 2016 This paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference frame phase locked loop (PLL).

Adaptive Impedance-Conditioned Phase-Locked Loop for the VSC Converter Connected to Weak Grid
Energies, 2021 In this paper, an adaptive version of the impedance-conditioned phase-locked loop (IC-PLL), namely the adaptive IC-PLL (AIC-PLL), is proposed. The IC-PLL has recently been proposed to address the issue of synchronisation with a weak AC grid by ...
