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…

Reduced Order Characterization of Nonlinear Oscillations Using an Adaptive Phase-Amplitude Coordinate Framework
Dan Wilson, Kai Sun
We propose a general strategy for reduced order modeling of systems that display highly nonlinear oscillations. By considering a continuous family of forced periodic orbits defined…
