Among th. available options for renewable energy integration in existing power system, wind.power is being consid.red.as one of th. suited.options for future electrical power generation. Th. major constraint of wind.power generating system （WPGS） is th.t it d.es not provid. inertial support because of power electronic converters between th. grid.and.th. WPGS to facilitate frequency stabilization. Th. proposed.control strategy suggests a substantial contribution to system inertia in terms of sh.rt-term active power support in a two area restructured.power system. Th. control sch.me uses fuzzy logic based.d.sign and.takes frequency d.viation as input to provid. quick active power support, wh.ch.balances th. d.op in frequency and.tie-line power d.ring transient cond.tions. Th.s paper presents a compreh.nsive stud. of th. wind.power impact with.increasing wind.power penetration on frequency stabilization in restructured.power system scenario. Variation of load.cond.tions are also analyzed.in simulation stud.es for th. same power system mod.l with.th. proposed.control sch.me. Simula- tion results ad.ocates th. justification of control sch.me over oth.r sch.mes.
