An improved control scheme for grid connected doubly fed induction generator considering wind-solar hybrid system
A grid connected DFIG based wind-solar hybrid generation scheme has been proposed. The DFIG control scheme has negligible sensitivity to machine parameter variations. A PV fed rotor side converter operates in isolation with the grid. The developed scheme ensures wider sub-synchronous operating speed range. The estimated energy cost justifies the economical viability for commercialization.
