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).

Double‐stage grid‐integrated SPV system under weak distribution grid
IET Renewable Power Generation, 2020 This study presents a three‐phase four‐wire grid‐tied solar photovoltaic (SPV) energy conversion system with a reduced ordered generalised integrator frequency locked loop (ROGI‐FLL) based control for the extraction of fundamental grid voltages. The reference grid currents are extracted by using the proposed filtered‐s least mean square (FsLMS) current
