Abstract :
This paper presents a robust STATCOM controller design for damping transients in a multi-machine power system. The method of multiplicative uncertainty is employed to model the variations in the power system operation. A graphical loop shaping technique incorporating a particle swarm optimization procedure has been used to realize the fixed parameter controller. A balanced realization based model reduction technique was used for reducing the order of the system. The robust design was implemented on a 4-machine system considering various loading and disturbance conditions. It is observed that the robust STATCOM controller provides very good damping profile for a wide range of operation
