Small Signal Modeling and Stability Analysis of Novel Grid Connected Z-Source Virtual Synchronous Generator (ZVSG)

摘要

In this paper, a novel Z-source virtual synchronous generator (ZVSG) is presented. The small signal model of the system is derived in synchronous reference frame and the stability of the grid connected converter is analyzed by using generalized Nyquist criteria in frequency domain. A realization of the proposed controller and converter has been done to confirm the stability results using Opal RT simulator.
