Abstract:
Lyapunov's direct method plays an important role as a very commonly used analytical tool in studies on transient synchronization stability (TSS) of grid-following converters. To bridge the gap that energy-type Lyapunov function (LF) is only effective in the positive damping area and thus too conservative, a novel LF whose domain of definition includes part of negative damping area is proposed for TSS analysis of grid-following converters. Its corresponding TSS criterion and estimated region of attraction (ROA) exhibit significantly reduced yet still guaran-teed conservativeness, endowing them with more practical value and higher efficiency in analytical TSS assessment works.
