This article presents the application of Taguchi robust design techniques for the tuning of power system stabilizers in a multi-machine power system. The power system stabilizer tuning is performed in two phases. In the first pre-elimination phase, the compound factor method is used to identify the significant and insignificant power system stabilizer parameters. In the second phase, only the significant power system stabilizer parameters are fine-tuned iteratively using the Taguchi optimization procedure. The efficacy of the proposed design technique has been evaluated on widely used a 10-generator, 39-bus New-England power system. [ABSTRACT FROM AUTHOR]

This article presents a new non-iterative approach to deal with the problem of robust tuning of power system stabilizers. The proposed approach is based on the Taguchi robust design technique, which aims at optimizing the power system stabilizer parameters while simultaneously reducing the influence of variations in system operating conditions. The robust tuning methodology of a single-stage power system stabilizer for the single-machine infinite-bus system is presented to demonstrate the Taguchi-based approach. The robust power system stabilizer parameters are determined using analysis of means. The robustness of the designed power system stabilizer is tested using no-way analysis of means and time domain simulations. [ABSTRACT FROM AUTHOR]
