A hybrid firefly algorithm and pattern search technique for SSSC based power oscillation damping controller design

(in lingua inglese)

An attempt has been made for the first time to apply a hybrid Firefly Algorithm (FA) and Pattern Search (PS) technique to design a SSSC based power oscillation damping controller. The input signal to the SSSC-based controller is derived from the locally measurable line active power. The design problem is formulated as an optimization problem and h-FAPS technique is employed to optimize the controller parameters. The effectiveness of the proposed SSSC controller in improving the power system stability is demonstrated for both single machine infinite bus and two-area four-machine power systems under various severe disturbances.
