K. Bhattacharya et al., TUNING OF POWER-SYSTEM STABILIZERS IN MULTIMACHINE SYSTEMS USING ISE TECHNIQUE, Electric power systems research, 46(2), 1998, pp. 119-131
The paper presents an approach based on integral of squared error (ISE
) technique for tuning of the parameters of power system stabilizers (
PSS) in a multi-machine power system. The PSS are tuned sequentially,
depending on which machine needs stabilization most. However, later it
has been establishes that if the tuning algorithm is iterated twice o
r more, no particular tuning sequence is necessary. Dynamic performanc
e with PSS tuned by the proposed method is compared with a previously
reported approach in which all the stabilizers are tuned simultaneousl
y. The proposed approach provides satisfactory system dynamic performa
nce and the method is computationally much simpler. (C) 1998 Elsevier
