The cascade line tripping is one of the main causes that can lead to power system breakdown. To avoid line tripping during the post-disturbance period, new fast algorithms are required. This paper describes a new approach to distributed coordination of FACTS which makes it possible to control power flow during the long-term transients. The proposed algorithm is based on the sensitivity analysis; it can be realized as a discrete-time controller and can be applied to different parts of a power system independently.
