In recent year, power generation from renewable energy sources is comming up. Particularly, wind power generation is attractive because of it's advantages like, pollution free, no fuel cost, abundantly available in nature etc. However, the generated power is fluctuating and it mainly depends on the wind speed. These fluctuations will arise the bus voltage fluctuations and will cause power oscillations. A superconducting magnetic energy storage (SMES) unit based on a self-commutated inverter using Gate-turn-off (GTO) thyristor is capable of controlling both the active and reactive power simultaneously and quickly. <BR>In this paper, control system conguration for active and ractive output power control of the series and parallel compensator which applied SMES is presented. Furthermore, this paper also describes the effectiveness of generating power leveling of transmission line and compensation of the generator's terminal bus voltage instantaneous sag. It is show through simulations, that the controlling sequence of charging and discharging of the SMES coil effectively damps out the generator's terminal bus voltage fluctuations and transmission line power oscillations.
