Abstract
Converter-grid interaction is of great interest in a weak-grid condition. In this paper, an alternative multi-input multi-output closed-loop system is developed for the stability analysis of grid-connected voltage-source converters. In contrast to the conventional dq-impedance model and the eigenvalue analysis, this model eventually yields a single-input single-output transfer function. This enables to apply a single Nyquist curve for analyzing the overall system stability. The model is validated against time-domain simulations and it shows excellent accuracy for predicting the system stability.
