Impact of PSS and STATCOM on dynamic parameters of power system based on neuro-fuzzy controllers

Abstract

This paper studies the impact of leveraging both static synchronous compensator (STATCOM) and power system stabilizer (PSS) on multi-machine power systems. Considering a standard IEEE 9-bus test power network, the classic and intelligent controllers are applied and analyzed to achieve a desirable system performance. Simulated tests show the usefulness of STATCOM on network power quality in terms voltage profile. In addition, it can significantly improve the damping oscillations of synchronous generator under normal and abnormal network conditions. The PSS also contributes to improving the synchronous generator parameters. It is also observed that using intelligent controllers with STATCOM and PSS leads to a better performance relative to the classic controllers.
