【Abstract】 A novel coordinate optimization method for optim izing PSS parameters in m ulti- machine power systems in terms of white noises is proposed. The m ethod can im prove the system damping by optimizing the PSS parameters,in which more than one generator are stim ulated by white noises and simultaneously reverse the non- linearity of the system model. Furthermore, it avoids the lim itation of conventional PSS design aiming atthe single oscillation frequency. Sim ulation results show that the proposed method can improve system damping in a wide range of system operating conditions.更多还原
