摘要

This study presents a simultaneous tuning of Power System Stabilizers (PSS) for enhancing the damping of low frequency electro-mechanical oscillations in a multi-machine power system using parameter-constrained non-linear optimization algorithm. The main objective of this procedure is to shift the undamped poles to the left hand side of the s-plane. In the proposed study, the parameters of each PSS controller are determined simultaneously using non-linear optimization technique. The objective of the simultaneous parameter tuning is to globally optimize the overall system damping performance by maximize the damping of all both local and inter area modes of oscillations. The results obtained from simultaneous coordinating tuning method validate the improvement in damping of the overall power system oscillations in an optimal manner. The time domain simulation results of multi-machine power system validate the effectiveness of the proposed approach. In this study, 10-machine 39-bus New England system is used as the test system.
