Performance Assessment of Thyristor Controlled Series Compensator (TCSC) in Sudanese National Grid

Abstract

In this thesis a method based on Particle Swarm Optimization (PSO) algorithm, which represents one type of modern optimization techniques is presented to determine the optimal parameters of Power System Stabilizers (PSSs) found in Sudanese National Grid, instead of classical control approaches. In addition TCSC is implemented in the National grid to increases the performance of the system by decreasing reactance of the transmission lines and hence increases the power flow in the lines as well as reduces the line losses. Optimal location for placing of TCSC is found by performance indices calculation to reduce overloading of each transmission line in normal case and contingency cases. TCSC improve system damping. The simulation carried out through MATLAB and POWER FACTORY software. Therefore as a result the TCSC enhance National Grid performance through decreasing transmission lines overloading under normal and contingency conditions. Also activation of power system stabilizers found in the National Grid and TCSC implementation had a significant role in enhancing damping in National grid.
