The execution of the contemplated OWF is reproduced by an equal doubly-fed induction generator (DFIG) driven by a proportional wind turbine (WT) while a comparable squirrel-confine rotor induction generator (SCIG) driven by an equal marinecurrent turbine (MCT) is utilized to recreate the qualities of the MCF. A damping controller of the STATCOM is planned by utilizing modular control hypothesis to contribute powerful damping attributes to the considered system under various working conditions. A frequency-area approach in view of a changed system display utilizing Eigen esteem strategies and a period space plot in view of a nonlinear system show subject to different unsettling influences are both utilized to reenact the adequacy of the proposed control conspire. It can be finished up from the reproduced comes about that the proposed STATCOM joined with the outlined damping controller is extremely successful to settle the contemplated system under aggravation conditions. The voltage fluctuations of the AC bus subject to the dynamic power varieties of the contemplated system can likewise be viably controlled by the proposed control plot.
