DOI: 10.1109/tpel.2025.3568790
Abstract: Oscillator-based grid-forming (GFM) control, such as dispatchable virtual oscillator and Andronov–Hopf oscillator control, offers a rigorous analytical framework with enhanced synchronization, lower harmonic, and faster dynamic response but lacks effective inertia support. Insufficient inertia will… read more here.
