Optimal tuning of power systems stabilizers and AVR gains using particle swarm optimization

摘要

In this paper, the problem of simultaneous and coordinated tuning of stabilizers parameters and automatic voltage regulators (AVRs) gains in multi-machine power systems is considered. This problem is formulated as an optimization problem, which is solved using particle swarm optimization technique. The objective of the parameters optimization is formulated as nonlinear problem with constraints to represent the allowable region of the system parameters. The effectiveness of the proposed technique for tuning of multi-controllers in a large power system is tested by applying it to the well-known New England system.
