Abstract
Integrating multiple parallel inverters introduces significant complexity into system dynamics, posing challenges for transient stability analysis of modern power system. This paper derives the Lyapunov functions for the multiple grid-following voltage source converter (multi-GFL-VSC) system, allowing us to investigate its transient stability analytically. The impact of inter-VSC coupling on system stability is considered. A novel stabilization method is proposed without requiring additional control loops in the presence of the limits of the phase-locked loop (PLL). Simulation results verify that inter-converter coupling can lead to cascading instability within the system and the proposed method can effectively stabilize it.
