Consideration of Control-Loop Interaction in Transient Stability of Grid-Following Inverters using Bandwidth Separation Method
Yifan Zhang, Yunjie Gu, Yue Zhu +3
Grid-following inverters have been widely adopted as a grid interface for renewable energy, and ensuring their small-signal and large-signal stability is critical to modern power s…
Descriptor State Space Modeling of Power Systems
Yitong Li, Timothy C. Green, Yunjie Gu
State space is widely used for modeling power systems and analyzing their dynamics but it is limited to representing causal and proper systems in which the number of zeros does not…
Whole-System First-Swing Stability of Inverter-Based Inertia-Free Power Systems
Yitong Li, Yunjie Gu
The emphasis on inertia for system stability has been a long-held tradition in conventional grids. The fast and flexible controllability of inverters opens up new possibilities. Th…
Impedance-based Root-cause Analysis: Comparative Study of Impedance Models and Calculation of Eigenvalue Sensitivity
Yue Zhu, Yunjie Gu, Yitong Li +1
Impedance models of power systems are useful when state-space models of apparatus such as inverter-based resources (IBRs) have not been made available and instead only black-box im…
The Intrinsic Communication in Power Systems: A New Perspective to Understand Synchronization Stability
Yitong Li, Timothy C. Green, Yunjie Gu
Synchronization is an essential element in three-phase ac electric power systems. The large-scale integration of converter-interfaced resources leads to the power grid transformati…
