Taxonomy of Power System Optimizations Issues With Power Systm Stabilizers: An Overview

This paper presents a survey of literature on the various optimization methods applied to solve the power system problem. A review and a methodology-based classification of most of the publications on the topic are presented. A Power System Stabilizer (PSS) is the most cost effective approach of increase the system positive damping, improve the steady-state stability margin, and suppress the low-frequency oscillation of the power system. A PSS has to perform well under operating point variations. Power System Stabilizers is to enhance the damping of low frequency oscillations in power systems. Low frequency oscillation problems are very difficult to solve because power systems are very large, complex and distributed geographically. Therefore, it is necessary to utilize most efficient optimization methods to take full advantages in simplifying the problem and its implementation. Many successful and powerful optimization methods and algorithms have been employed to solve this problem. These optimization methodologies and techniques are widely diverse and have been the subject of ongoing enhancements over the years. However, Optimization techniques proved to be able to overcome these limits.
