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…
