A Grid Connected Flicker Compensation of DFIG for Power Quality Improvement by using Ann

For the rotor side converter (RSC) of doubly fed induction generators (DFIGs) a novel terminology called combined vector and direct power control (CVDPC) is considered. The control system is resultant of a direct current control through proper voltage vectors selection from a switching table. In reality, the proposed CVDPC has the advantage of vector control (VC) and direct power control (DPC) in a compressed control system. Its advantage in contrast with VC consists of quick dynamic outcomes, toughness besides the machine factors modification, reduced computation and minimal realization. Alternatively it includes serves in relation to DPC, with fewer harmonic alteration as well as decreased power fluctuation. A vast simulation analysis by means of MATLAB/Simulink is performed on a 9-MW wind plant made of six 1.5 MW DFIG basis wind turbines. The operation of the proposed CVDPC technique is compared through both VC and DPC during steady-state and transient state. Simulation outcomes verify the dominance of the CVDPC over both VC and DPC.
