Matrix-Valued Passivity Indices: Foundations, Properties, and Stability Implications
Xi Ru, Xiaoyu Peng, Xinghua Chen +3
The passivity index, a quantitative measure of a system's passivity deficiency or excess, has been widely used in stability analysis and control. Existing studies mostly rely on sc…
Controlled Evolution-Based Day-Ahead Robust Dispatch Considering Frequency Security with Frequency Regulation Loads and Curtailable Loads
Kai Kang, Xiaoyu Peng, Kui Luo +2
With the extensive integration of volatile and uncertain renewable energy, power systems face significant challenges in primary frequency regulation due to instantaneous power fluc…
Compositional and Equilibrium-Free Conditions for Power System Stability -- Part II: Method and Application
Peng Yang, Yifan Su, Xiaoyu Peng +2
This two-part paper proposes a compositional and equilibrium-free approach to analyzing power system stability. In Part I, we have established the stability theory and proposed sta…
Compositional and Equilibrium-Free Conditions for Power System Stability -- Part I: Theory
Peng Yang, Xiaoyu Peng, Xi Ru +2
Traditional centralized stability analysis struggles with scalability in large complex modern power grids. This two-part paper proposes a compositional and equilibrium-free approac…
