Variable Structure Power System Stabilizer Optimized by Genetic Algorithm

Year 2011, Volume: 6 Issue: 1, 274 - 285, 01.02.2011

Abstract

In this study, an optimal variable structure power system stabilizer (VS-PSS) is proposed in order to improve dynamic stability of single machine infinite bus (SMIB) system. Model uncertainties, parameter variations, and external disturbances always exist in power systems. Therefore, variable structure control (VSC) is considered as a robust control method for designing PSS. Performance and robustness of VSC system depend on switching function and feedback gains. That's why; they are optimized via genetic algorithm (GA). The proposed VS-PSS is based on a state-space model which derived from Philps-Heffron model. It is seen that the VS-PSS improve the dynamic stability of power system better than conventional PSS according to simulation studies done under different external disturbance conditions.

GA ile Optimal De?i?ken Yapyly Güç Sistem Kararlayycysy Tasarymy

Year 2011, Volume: 6 Issue: 1, 274 - 285, 01.02.2011

Abstract

Bu çaly?mada, sonsuz baraya ba?ly bir senkron generatörün (SBSG) dinamik kararlyly?yny iyile?tirmek için optimal bir de?i?ken yapyly güç sistemi kararlayycysy (DY-GSK) sunulmaktadyr. Güç sistemlerinde model belirsizlikleri, parametre de?i?imleri ve bozucu etkiler devamly bulunur. Bu yüzden, GSK tasarymy için dayanykly bir kontrol yöntemi olan de?i?ken yapyly kontrol (DYK) yöntemi önerilmi?tir. DYK sisteminin performansy ve dayanyklyly?y anahtarlama fonksiyonuna ve geribesleme kazançlaryna ba?lydyr. Bu nedenle, DY-GSK'nyn anahtarlama fonksiyonu ve geribesleme kazançlary genetik algoritma (GA) ile optimize edilmi?tir. Önerilen DY-GSK, SBSG'nin do?rusalla?tyrylmy? Philips-Heffron modelinden türetilen durum uzay modeline dayandyrylmy?tyr. Yapylan benzetim çaly?malarynda önerilen DY-GSK'nyn farkly bozucu durumlarynda klasik GSK'ya göre güç sisteminin dinamik kararlyly?yny daha iyi geli?tirdi?i gösterilmi?tir.
