A Physics-Informed Neural Network for Small-Signal Stability in Multi-Inverter Power Systems
Hanxi Chen, Xiangyu Meng, Jianhong Wang +1
The whole-system impedance model has proven a powerful tool for assessing the small-signal stability of multi-inverter power systems; however, its application is limited to a small…
Stability and Droop Characteristics Analysis of Observer-Synchronized Grid-Forming Control
Aizuo Chen, Xiangyu Meng, Yue Zhu
This paper analyzes the stability and droop characteristics of Observer-Synchronized grid-forming control. First, a second-order nonlinear autonomous model is derived under the qua…
An Admittance-Based Inverter Connection Screening Tool for Small-Signal System Strength
Andreas Hadjileonidas, Debargha Brahma, Yue Zhu +1
The increasing occurrence of small-signal instability, particularly sub-synchronous oscillations (SSOs), in power systems with a high penetration of inverter-based resources (IBRs)…
Large-Signal Stability of Power Systems with Mixtures of GFL, GFM and GSP Inverters
Yifan Zhang, Yaoxin Wang, Yunjie Gu +5
Grid-following (GFL) inverters have very different large-signal stability characteristics to synchronous generators, and convenient concepts such as the equal-area criterion and gl…
