Transient Simulation of Distribution System with Converter-Based
Distributed Generation for Stability Analysis Using Frequency Response
This paper introduces a novel transient simulation scheme and its
extension for stability analysis of distribution systems with
converter-based distributed generation. Efficiency and accuracy of the
simulation scheme with extension are investigated. It is demonstrated
that millisecond-level step sizes are applicable to efficient
electromagnetic transient simulation for stability analysis of
unbalanced power systems while maintaining satisfactory accuracy. The
paper also supports the extension of the simulation scheme by showing
that the extension has only an insignificant impact on the accuracy but
significantly enhances the efficiency.
