Abstract
This paper presents an extensive survey on the existing cases, system studies and assessment techniques to help system planners understand the underlying mechanism of diverse interactions among multiple FACTS controllers and develop coordinated control schemes for preventing or mitigating any harmful interactions. This paper presents in-depth review of several literatures in regarding with interaction problems and various techniques for coordinated control between PSS and FACTS controllers or FACTS to FACTS controllers in power system environments. It may also be effective in transient stability improvement, power oscillations damping and balancing power flow in parallel lines. It has been noticed that adverse interactions among multiple FACTS controllers may occur when they are not properly coordinated with each other and other slowly acting system equipment.
