Improved control strategies for a DFIG-based wind-power generation system with SGSC under unbalanced and distorted grid voltage conditions ?
Performance of DFIG with SGSC under unbalanced and distorted voltage are enhanced. Three sets of selectable control targets for PGSC are identified. Allocations for the PGSCs current references is studied by considering its limit. PI-DFR controller are designed to regulate corresponding components simultaneously. Realize generator under normal operation and suppress pulsations of output powers.
