基于端口哈密顿框架的构网型逆变器无源控制设计

This article presents a modified dispatchable virtual oscillator control approach for achieving the passivity of grid-forming inverters (GFMs), without assuming constant voltage and constant frequency. The proposed control framework utilizes the port-Hamiltonian (PH)–based structure that mimics the behaviors of coupled harmonic oscillators, along with an energy “pumping-or-damping” block and the c...
