Isostable-Based Nonlinear Model Reduction for Power System Oscillations
Kaiyang Huang, Dan Wilson, Kai Sun
Power systems are often represented by high-dimensional dynamic models, making nonlinear control design computationally expensive and limiting its practical application. Oscillatio…
Reduced-Order Model Characterization of Nonlinear Sustained Oscillations
Kaiyang Huang, Dan Wilson, Kai Sun
Nonlinear sustained oscillations involving inverter-based resources can happen when device and network interactions produce an attracting limit cycle around an unstable equilibrium…
Reactive Power Beyond Sinusoids: Scalar Measurement Readouts and Information Limits
Kai Sun
Reactive power is not uniquely defined for nonsinusoidal voltage and current waveforms because different scalar readouts can assign different values to the same measured voltage--c…
Why Three Phases? A Historical and Engineering Reassessment of Phase Order in AC Power Transmission
Kai Sun
Three-phase alternating current is so deeply embedded in modern electric-power infrastructure that its phase order is often treated as self-evident. Historically, however, 1-phase…
A Benchmark on LLM-Based Power Flow Computation: Do More Structured Prompts Help?
Tingwei Chen, Kaiyang Huang, Kai Sun
We present a controlled benchmark evaluating three LLMs -- Claude Sonnet 4.5, Gemini 2.5 Pro, and GPT-3.5 Turbo -- across four prompt formats (from concise narrative to structured…
Efficient High-Order Participation Factor Computation via Batch-Structured Tensor Contraction
Mahsa Sajjadi, Kaiyang Huang, Kai Sun
Participation factors (PFs) quantify the interaction between system modes and state variables, and they play a crucial role in various applications such as modal analysis, model re…
A Heterogeneous Multiscale Method for Efficient Simulation of Power Systems with Inverter-Based Resources
Kaiyang Huang, Min Xiong, Yang Liu +1
As inverter-based resources (IBRs) penetrate power systems, the dynamics become more complex, exhibiting multiple timescales, including electromagnetic transient (EMT) dynamics of…
PI-Controlled Variable Time-Step Power System Simulation Using an Adaptive Order Differential Transformation Method
Kaiyang Huang, Yang Liu, Kai Sun +1
Dynamic simulation plays a crucial role in power system transient stability analysis, but traditional numerical integration-based methods are time-consuming due to the small time s…
A Semi-Analytical Approach for State-Space Electromagnetic Transient Simulation Using the Differential Transformation
Min Xiong, Kaiyang Huang, Yang Liu +3
Electromagnetic transient (EMT) simulation is a crucial tool for power system dynamic analysis because of its detailed component modeling and high simulation accuracy. However, it…
