This paper addresses a novel control strategy dependent static synchronous compensator (STATCOM) to intensify power quality for efficacious power transfer and frequency control of a grid-pertinent wind farms. This proposed system consist of two wind power generating systems in which one generator replicated by an commensurate doubly-fed asynchronous generator operated by an tantamount wind turbine while other generator is simulated by an squirrel-cage rotor asynchronous generator driven by wind turbine. The dynamic changes in load will create dearth for active and reactive power at load bus resulting in variations in frequency and magnitude load voltage. This quandary can be elucidated by amalgamating the modifiable reactive power fount (STATCOM) at load bus so that voltage can be regulated, simultaneously the reactive power strain on wind farm is reduced so that active power injected in to grid increases which stabilizes the grid frequency. Three conditions are designed (I) autonomous mode, (II) grid- amalgamated mode and (III) grid-amalgamated mode with STATCOM, are examined to juxtapose their dynamic and transitory behavior. From Results it can be observed that case-III best contended the dynamic recompense demand out of all conditions.
