Placement Of Thyristor Controlled Series Compensator Research Articles

A new method for locating TCSC for congestion management in deregulated electricity markets

This paper presents the effects of thyristor controlled series compensator (TCSC) on congestion of transmission lines and locational marginal price (LMP) in deregulated power systems. The placement of TCSC is to reduce congestion in deregulated electricity markets based on the calculation of congestion rent. The main objective of TCSC placement is either to minimise congestion rent or to maximise social welfare. Genetic algorithm-based optimal power flow (OPF) algorithm is used to maximise social welfare for finding the best location and rating of TCSC and the results obtained are compared with conventional LMP method. A sample five bus test system is used to show the influence of TCSC on congestion and LMP in the electricity market and for finding best location for TCSC placement.

Application of Trajectory Sensitivity for the Evaluation of the Effect of TCSC Placement on Transient Stability

This paper investigates the use of trajectory sensitivity analysis (TSA) technique for assessing the transient stability of a power system at various operating conditions. The effect of placement of a thyristor controlled series compensator (TCSC) as well as the influence of the change in firing angle is also discussed. The TCSC is modeled by a variable capacitor, the value of which changes with the firing angle. The systems studied are the WSCC 3-machine, 9-bus system and IEEE 16 machine 68 bus system. The results using TSA are validated by PSCAD/EMTDC simulation.
