Damping of Power System Oscillations via Quantum Particle Swarm Optimization Based Distributed Static Series Compensator

Abstract

The distributed static series compensator is a series distributed flexible AC transmission system device that can control the power flow in the transmission lines. In this article, a linear Heffron–Philips model for a distributed static series compensator is presented and considered to design a supplementary damping controller for low-frequency oscillations in a single- and multi-machine power system. A quantum particle swarm optimization based damping controller is designed for the distributed static series compensator to damp the power system oscillations. To compare the results, a particle swarm optimization based damping controller is also designed and granted to the distributed static series compensator to damp the oscillations. Simulation results are performed in two separate cases. In the first case, the quantum particle swarm optimization based damping controller is examined in a single-machine infinite bus based on the linearized model of the system in three different operating points; in the second case, non-linear time-domain simulations have been performed in a six-machine three-area power system. Moreover, performance index analysis is also carried out to verify the effectiveness of the proposed quantum particle swarm optimization based damping controller.
