Optimal Placement and Sizing of Thyristor-controlled-series-capacitor using Gravitational Search Algorithm
Abstract: This paper
represents the Gravitational Search Algorithm (GSA) that can be used to
determine the optimal location and rating of Thyristor controlled Series
Capacitor (TCSC). TCSC is equipment used to regulate and improve power flow in
power system. The method used in this study was GSA. TCSC were the implemented
on 500kV Java-Bali Power System. Loadflow results before optimization using
Newton Rapshon method showed that active power loss was 297.607MW. While
loadflow results after optimization using GSA with 5-TCSC obtained were
287.926MW of active power loss, with 10-TCSC, it was obtained 281.143MW of
active power loss. In addition, using 15-TCSC, active power loss obtained was
279.405MW. GSA methods can be used to minimize power losses and transmission
lines as well as to improve value of voltage in the range of 0.95+ 1.05pu
compared with loadflow results before optimization.The more TCSC is used, then
value of active power losses small.
