Frequency-Domain Participation Analysis for Electronic Power Systems
Yicheng Liao, Xiongfei Wang, Xiao Wang
Abstract
This letter proposes a frequency-domain participation analysis approach to identifying the root cause of small-signal instability for electronic power systems. Differing from the participation analysis based on state-space analysis, the proposed approach is implemented based on impedance models, which is, thus, readily applicable for large-scale systems only with black-box models. The theoretical analysis is finally verified by the simulations and experiments.
