摘要：
In this letter, we propose a sensitivity method for small-signal stability analysis of the nonlinear time-periodic (NLTP) system through its harmonic state-space model. This method addresses the limitations of traditional sensitivity methods, which only apply to specific NLTP systems, thus facilitating sensitivity analysis in power electronics-dominated power systems (PEPS). A case study conducted in a real-world multimachine PEPS validates the proposed method by RT-LAB.
