A distributed control of FACTS devices against line overloading

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.
