DFIG Virtual Inertia Frequency Control Strategy

Article Preview

Abstract:

During the DFIG maximum power tracking control process, the rotor side converter is only based on the wind turbine speed to regulate the active power output; it almost no provides effective inertia. DFIG could add auxiliary virtual inertia control system, when the system frequency is reduced, releasing the rotor "hidden" kinetic energy to support the grid dynamic frequency.
