Static Security Enhancement and Loss Minimization Using Simulated Annealing
In this paper the authors present a developed algorithm for optimal placement of Thyristor Controlled Series Capacitors (TCSC's) for enhancing the power system static security and minimizing the system overall power loss. Placing TCSC's at selected branches requires analysis of the system behavior under all possible contingencies. A selective procedure to determine the locations and settings of the thyristor controlled series capacitors is presented. The locations are determined by evaluating Contingency Sensitivity Index (CSI) for a given power system branch for a given number of contingencies.
