Modeling of Wind Energy Conversion System Including DFIG for Distributed Generation Studie

A detailed model of wind power station، including double fed induction generator، dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used for the simulation. the simulation model is used to investigate the performance of controllers under wind speed variations، short circuit at the grid side and dynamics of active power demand.
