Application of TCSC to improve total transmission capacity in deregulated power systems

An important issue in large power markets is the optimization of total transmission capacity (TTC). This paper presents a genetic approach for the placement of one Thyristor controlled series capacitor (TCSC) in deregulated power systems to increase TTC and improve the voltage stability. Detailed analysis is presented for multi-machine networks with multiple power-sellers and multiple power-buyers (power-consumer). Simulation results before and after compensation are used to analysis the impacts of TCSC on the IEEE 14-bus test system under deregulated conditions.
