Abstract

This paper analyzes the synchronization stability of grid-forming converter. The impact of line impedance on small-signal stability is analyzed through the Routh criterion. Moreover, the stable and unstable regions are explicitly identified on the complex impedance plane, providing clear insights into the stability evaluation. Based on the analysis, a virtual inductance is synthesized to guarantee the synchronization stability without knowing line impedance information. The effectiveness of the proposed approach is verified by preliminary experimental results.
