基于LTP理论的变换器主导电力系统稳定性分析的截断阶数选择方法

This letter addresses eigenvalue calculation of linear time-periodic models for small-signal stability analysis of converter dominated power systems. An adaptive truncation order selection method is proposed to achieve a balance between computational accuracy and efficiency. Rigorous theoretical analysis and case studies on a grid-following voltage source converter and a modified IEEE 13-bus syste...
