doi:10.3969/j.issn.1000-7229.2019.10.007

Abstract

Abstract: Subsynchronous oscillation occurred in the on-grid wind farms has seriously affected the stability of the whole system and has become a bottleneck to the efficient utilization of wind power. This problem attracts wide attentions from both the industry and the academia. Different study methods have been presented in the literature. In this paper， various analysis methods for subsynchronous oscillations associated with wind power are classified into two categories， namely time domain and frequency domain. A comprehensive review of the methods is given， including their practical application in China and abroad. Considering the fact that the impedance model-based analysis method has received extensive attention recently， the paper focuses on the impedance analysis method and summarizes the latest research results of impedance modeling and stability criteria. Meanwhile， new challenges or open problems are summarized. The direction for future research work is also discussed.

Key words: on-grid wind power systems, subsynchronous oscillation, time domain, frequency domain, impedance analysis method
