Research Progress on Interaction and Coordinated Control Among FACTS Controllers

With wide application of flexible AC transmission system(FACTS) technology and devices in large-scale interconnected power system,it is very important to investigate the interaction and coordinated control among FACTS controllers.This paper gives the definition of interaction among FACTS controllers,introduces various types of interactions involved in current studies on FACTS controllers,sums several practical methods for analyzing these interactions,finally reviews coordinated control methods on FACTS controllers,and points out some new research topics which require more attention in future studies.
