Three-phase fault analysis of power system transient stability based on TCSC controller using FPA for its location

Abstract Preventing the power system from becoming overloaded and under stress to point where it is on verge of reaching limits its transient stability due high consumption. This paper proposed dynamic security assessment for using Thyristor controlled series capacitor (TCSC) devices controller. The criteria are based severity indices analyzing fault in system. index uses time domain analysis simulation, making easier simpler implement operators better prepare potential disturbances by anticipating how systems will behave. optimal location parameters setting TCSC was determined Flower Pollination Algorithm (FPA) higher convergence rate. tested IEEE 14-bus further discusses effect a three-phase short circuit fault, different locations, clearing method. An done determine faults lines affect voltage load bus generator findings show that employing TCSC, drop acceptable improved margins were greatly increased.
