Abstract :
In this paper, designing and application of an
optimal supplementary controller for damping of power
swing in a weakly connected power system. The
proposed stabilizer is a SSSC based controller that is
designed based on a hybrid PSO and GSA algorithm. The
behavior of proposed controller under different loading
operating conditions is also investigated. The
effectiveness of proposed controller on enhancing
dynamic stability is tested through modal analysis and
time domain simulation. Also, nonlinear and electrical
simulation results show the validity and effectiveness of
the proposed control schemes over a wide range of
loading conditions. It is also observed that the proposed
SSSC based damping stabilizers greatly enhance the
power system transient stability. The simulation results of
coordinated design of stabilizer based on ? and m is also
presented and discussed. The system performance
analysis under different operating conditions shows that
the ?-based controller is superior to the m-based
controller.
