Transient Simulation of Distribution System with Converter-Based Distributed Generation for Stability Analysis Using Frequency Response Optimized Integrators
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.
