Abstract

An intelligent optimization algorithm called self-adaptive weightiness particle swarm optimization（SWPSO）is applied to obtain optimal parameters of power system stabilizer PSS4B-W

and the parameter optimization model for PSS4B-W is established.By adjusting weightiness dynamically

better global search ability is achieved.According to the single machine infinite system model

on the basis of calculating phase frequency characteristic without compensation of excitation system

the parameter optimization model is used to calculate phase compensation of PSS4B-W.The simulation results show that optimized PSS4B-W can suppress low frequency oscillation well and increase power system stability.
