ABSTRACT:
In this paper, the Particle Swarm Optimization (PSO) technique is used to develop a
controller for damping power system oscillations. The speed deviation Δω and its rate of
change
•
Δω are selected as input signals to the proposed controller. The objective is to get
optimal gains values of the controller within pre-specified limits to improve the system
dynamics.
In order to ensure the reliability of the PSO based controller, a comparison has been made
between the effect of the developed controller and that of an ℋ∞ controller on the dynamic
performance of a single machine connected to infinite bus. The simulation results show that
the PSO-based controller offer effective damping to system oscillations in a wide range of
operating conditions and system parameters.
