Application of PSS and FACTS Devices for Intensification of Power System Stability

Power demand has risen considerably in recent years, while the development of power generation and transmission has been seriously restricted due to limited resources and environmental limitations. Power system stabilizers (PSS) and flexible AC transmission system (FACTS) devices are applied to increase the system stability. Use of only conventional PSS in large multi-machine systems may not supply satisfactory damping for inter-area oscillations. In this situation, FACTS power oscillation damping controllers are efficient solutions. The literature shows an increasing interest in this topic for the last two decades, where the enhancement of system stability using FACTS controllers has been widely investigated. In addition coordination between PSS and FACTS controllers have been explored This paper provides an extensive review on the research and improvements in the power system stability enhancement using PSS and FACTS controllers. Several technical publications related to FACTS installations have been highlighted and performance comparison of different FACTS controllers has been discussed Moreover, some of the utility experience, real-world installations, and semiconductor technology development have been outlined Applications of PSS and FACTS to other power system studies have been surveyed About three hundred sixty research publications have been sorted and appended for a rapid reference.
