Output Stabilization of Wind Turbine Generator by Series and Parallel Compensation Using SMES.

Abstract

In recent year, the generating power from renewableenergy sources is coming up. Particularly, wind energy conversionsystems is at tractive becau se of it's advant ages such as , pollutionfree, no fuel cost, ab undantly available in natu re etc,However, thegenerated power and the bus voltage is always fuctuating and itmainly depends on the wind speed，A su perconducting m agneticenergy storage(SMES] unit is capable of controlling both the ac-tive and reactive po wer simultaneously and quickly. In this paper.contro! scheme for active and reactive output power simultan eouscontrol and voltage cont rol of t he series an d parallel com pensat orusing SMES is proposed. It is show through sim ulations, that thecontrolling sequence of charging and disch argin g of the SMES coileffectively damps out the transm ission line power oscillation an dwTG's termin al bus yoltage fuctuations.
