As the share of inverters in the power system increases, the stability of inverters has an increasing impact on the reliable operation of power electronics dominated power systems. Since the synchronization mechanism plays a leading role in the dynamic performance of the inverter, its stability is one of the keys for the stable operation of the power system. The Grid Forming inverters have emerged in recent years, is completely different from the traditional Grid Following inverter in terms of synchronization mechanism. This paper will analyze and compare the differences in transient stability between the synchronization mechanisms of the two concepts of inverters through large-signal modelling and phase-portrait method. The analysis results show that the Grid Forming inverter is more robust in synchronization mechanism.
