该研究指出电力系统中基于无源性的分布式稳定性分析受相对次数壁垒限制,无法适配含电磁暂态的高保真逆变器模型,并探讨了突破该局限的无源性框架扩展方向。
中文摘要 AI 辅助
本通讯揭示了电力系统中基于无源性的分布式稳定性分析存在的根本局限:在标准框架下,无源性认证固有地施加了相对次数兼容性约束,排除了许多高保真逆变器动态模型(例如包含电磁暂态的模型),文中还讨论了无源性框架的潜在扩展以突破该局限。
英文摘要
This letter reveals a fundamental limitation of passivity-based distributed stability analysis in power systems. Under the standard formulation, passivity certification inherently imposes a relative-degree compatibility constraint that excludes many high-fidelity inverter dynamic models (e.g., those that include electromagnetic transients). Potential extensions of passivity frameworks are discussed to break this limitation.
