Wide-area damping control for inter-area oscillations: A comprehensive review

Inter-area oscillation problem is one of the major stability issues that face interconnection of the power systems. Recent development in wide-area measurement systems (WAMS) provides a great potential to overcome the shortcomings of conventional local controllers and it makes using of remote signals as inputs for controllers feasible. This paper provides a survey of recent research and developments in the field of wide-area control for inter-area oscillation damping. Main designing procedures of wide-area damping controller and challenges face each step have been reviewed. Moreover, new researchers can follow recent and future trends in the area of wide-area damping control system.
