A Novel Inter Connection of DFIG with Grid in Logic Control
... One characteristic of the DFIG-based wind turbine system is the bidirectional power flow of the rotor. When ωr >ωs, the power flows from the rotor to the power grid. When ωr <ωs, the rotor absorbs the energy from the power grid. Similar to a traditional power system, the stator of the generator dire ...
