abstract
While power flow between buses cannot be directly controlled, the use of Flexible AC Transmission systems allow a reasonable degree of control of power flow in the lines through changes in the effective impedance of the line. In cases of failure of Distributed FACTS [1], where they fail to inject the reactive power that is expected, the lines can be overloaded or have flows that create unstable bus voltages. This paper proposes an algorithm to modify the settings of the other D-FACTS controllers in the system to achieve stable operation, given the failure of one or more distributed controller (malicious or benign). This paper presents results for corrective operation settings for D-FACTS controller that can be extended to other FACTS.
