Abstract


Power system stabilizer (PSS) and flexible AC transmission system (FACTS) damping
controller to improve the stability of the power system has been widely used. A coordinated
control method based on the combined computational evolutionary theory is proposed to
overcome some of damping controllers simultaneously so as to keep the allowable level of
power system damping. It works by making full use of favorable interaction between the
controlling and minimizing adverse interactions so that the power system oscillations can be
suppressed effectively. Proportional integral derivative (PID) controller tuning based power
system stabilizer types PSS3B (PIDPSS3B), static var compensator (SVC) and automatic
voltage regulator (AVR) presented in this paper. PID controller gain parameters such as
proportional, integral factor, differential coefficient and get AVR selected and optimized by
BF-PSOTVAC. The integral time absolut error (ITAE) standards of optimization design as
objective function. The results of simulations show that performance index of system the
proposed method is 42.7890. The BF-PSOTVAC method has the capability to damping
optimally and suppresses error to minimum.
