Flawless Attuning for Parameters of Power System Modulator Applying Grey Wolf Optimization

Abstract

Flawless attuning for the parameters of the power system regulator/ stabilizer / modulator is presented in the paper. The attuning of parameters in the power system modulator (PSM) becomes a prerequisite to have a stable and reliable performance across a broad scope of operating as well as system conditions. The parameter choices in the PSM for concurrently stabilizing the oscillation in the system is often transformed into an unpretentious optimization issue. This optimization issue in the proposed method is solved by foraging behaviors of the grey wolves. The proficiency of the mechanism devised in the paper is evaluated with two test cases of a Multi-device system encompassed with two machines and four buses. The results observed from the test cases prove that the attuning of the parameters using the foraging behavior of the grey wolves is a smart another to the traditional-FGM (fixed gain modulators/stabilizers). The experimental outcomes for the proposed method shows that the parameter attuning devised by the GWO affords to deliver a most compatible, reliable and a stabilized overall system performance compared to the traditional techniques.
