Constructive Port-Hamiltonian Energy Shaping Design of Dispatchable Virtual Oscillators in Grid-Forming Converters
Lu Gao, Lihui Yang, Feng Ji +2
Port-Hamiltonian (PH) theory offers a passivity-based framework for grid-forming control, yet conventional dispatchable virtual oscillator control (dVOC) does not naturally admit a…

From Rigid to Adiabatic: Canonical Regularization of AC Networks via Action-Angle Variables
Feng Ji, Lu Gao, Lihui Yang
Traditional power system analysis relies on timescale separation and the rigid-network assumption, freezing electromagnetic transients into algebraic power-flow equations via Stein…

Effective Numerical Simulation of Fault Transient System
Sixu Wu, Feng Ji, Lu Gao +3
Power systems, including synchronous generator systems, are typical systems that strive for stable operation. In this article, we numerically study the fault transient process of a…
