Optimal Location and Parameter Selection of Thyristor Controlled Series Capacitor Using Particle Swarm Optimization.

This paper proposes the optimal location of Thyristor Controlled Series Capacitor (TCSC) to reduce the active power loss in radial distribution system using Particle Swarm Optimization (PSO) algorithm. Also in this work, reactance characteristics curve of a TCSC device is drawn between effective reactance of TCSC (X-TCSC) and firing angle 'alpha' from the optimal output obtained from the PSO algorithm. This gives the effective value of the firing angle 'alpha' and the main parameters of TCSC (such as X-C and X-L) are also designed. This analysis is done by degree of series compensation 'k'. The feasibility and effectiveness of the optimization methods proposed have been demonstrated on 12, 34 and 69 bus radial distribution system consisting of 11, 33 and 68 sections respectively. MATLAB, Version 7.10 software is used for simulation.
