Abstract

With the inter connection of the power system, the complexity increases day by day. The increasing of the load also favors to the complexity of power system. The complexity of the power system can easily handled by analyzing the performance of the transmission system by using load flows. The real and reactive power losses are largely effected at the transmission level. With the advancement in power electronics the advanced compensation devices are improved which are called FACTS. The improvement of voltage profile effects on the reactive power losses of the transmission system. With the series compensation to the system the reactive power losses are reduced by maintaining the voltage profile within the constraints. Thyristor controlled series capacitor (TCSC) is used in firing angel mode to maintain the voltage profile with in constraints. In this paper a new method called optimization is proposed to select the suitable location of TCSC, firing angle of TCSC and size of the TCSC are determined by different optimizing techniques to the same Objective function. This paper proposes the heuristic Algorithms such as Genetic algorithm, Particle Swarm Optimization and Dragonfly algorithm method for selection of the suitable branch, suitable firing angle of the thyristor in TCSC and size of the TCSC.
