摘要：In this paper, genetic algorithm (GA) opmization
technique is applied to design Flexible AC Transmission System
(FACTS)-based damping controllers. Two types of controller
structures, namely a proportional-integral (PI) and a lead-lag (LL) are
considered. The design problem of the proposed controllers is
formulated as an optimization problem and GA is employed to search
for optimal controller parameters. By minimizing the time-domain
based objective function, in which the deviation in the oscillatory
rotor speed of the generator is involved; stability performance of the
system is improved. The proposed controllers are tested on a weakly
connected power system subjected to different disturbances. The
non-linear simulation results are presented to show the effectiveness
of the proposed controller and their ability to provide efficient
damping of low frequency oscillations. It is also observed that the
proposed SSSC-based controllers improve greatly the voltage profile
of the system under severe disturbances. Further, the dynamic
performances of both the PI and LL structured FACTS-controller are
analyzed at different loading conditions and under various
disturbance condition as well as under unbalanced fault conditions..
