Abstract

This paper presents the design and performance
analysis of a meta-heuristic search technique (Gravitational-Search-algorithm)
to optimal tuning of Proportional-Integral-Derivative plus Filter (PIDF)
controller for automatic generation control. The designed algorithm is applied
in multi-source interconnected power system. The system under investigation is
equipped with PIDF-controllers which are widely used in literature considering
for the analysis and design purpose. Excellency of the proposed approach is shown
with comparison of differential evolution and particle swarm optimization
algorithm. The dynamic response has been studied under variety of operating-conditions.
The simulation results represent that the tuned PIDF-controllers by
gravitational search algorithm supply the better damping of oscillations in
power system.
