On Dimension-Varying Control Systems: A Universal State Space Approach
Feng Liu, Daizhan Cheng, Xiaoming Hu +1
This paper develops a unified framework for the analysis and design of dimension-varying control systems by constructing an intrinsic quotient state space, . A significant chal…
When Can Phasor-Domain Device Models Be Trusted for Electromechanical Stability Analysis of Grid-Forming Converter-Dominated Microgrids?
Zhongze Li, Xiaoyu Peng, Xi Ru +4
Grid-forming (GFM) converter-dominated microgrids are often analyzed using reduced-order phasor-domain electromechanical GFM models, but the validity of these models is often taken…
Quantifying Uncertainty in Space Debris Capture with Active Tether-Net Systems Caused by Noisy Observations
Feng Liu, Achira Boonrath, Eleonora M. Botta +1
As Low Earth Orbit has grown more crowded with space debris, the need for reliable and efficient debris removal solutions becomes more urgent. An active tether-net system with mane…
A Non-Iterative Algorithm for Clearing Two-Layer Energy-Sharing Markets with Voltage Constraints
Tonghua Liu, Yifan Su, Zhaojian Wang +1
Real-time hierarchical energy-sharing markets are promising to coordinate large numbers of prosumers. Still, most existing clearing methods rely on linearized or DC power-flow mode…
Extreme Scenario Characterization for High Renewable Energy Penetrated Power Systems over Long Time Scales
Kai Kang, Feng Liu, Yifan Su +1
Power systems with high renewable energy penetration are highly influenced by weather conditions, often facing significant challenges such as persistent power shortages and severe…
