AB - Inverter-based resources (IBRs) operating in gridfollowing (GFL) mode are particularly vulnerable to instabilities in weak grid conditions. This is largely due to the inherent limitations of synchronization with a phase locked loop (PLL). This paper presents a novel voltage magnitude-based synchronization (VMSync) method that ensures stable and well damped response even in very weak grid conditions, without compromising dynamic performance or adding any stabilization control components. Through comprehensive frequency- and time-domain analysis, VMSync is shown to outperform conventional synchronous reference frame PLL (SRF-PLL) for both small- and large-signal disturbances. Systems with multiple GFL inverters employing VMSync demonstrate significantly improved damping and stability. Furthermore, mixed deployment of VMSync alongside legacy SRF-PLL-based GFL inverters exhibits superior dynamic performance compared to deployment of solely SRF-PLL-based GFL inverters. The results highlight the potential of VMSync as a robust synchronization strategy to mitigate PLL-driven instabilities in power grids with high IBR penetration.
