A Study on Power System Stabilization using H<SUB>∞</SUB> Optimal Control Method

  In this paper, we are considered various possible disturbance conditions in order to design controller, H<SUB>∞</SUB> optimal controller is successfully designed to control in such as situations. To do this, we are determined weighting function and design parameter γ to method of trial and error by Glover-Doyle algorithm. To compare with H<SUB>∞</SUB>-PSS and conventional-PSS which is applied in nominal system and load variations, the dynamic characteristics of H<SUB>∞</SUB>-PSS controller was verified which has a good response.
