Abstract :
Transmission system congestion is serious issue for the Independent System Operator (ISO) as it violates the various operating limits of the system. It may also cause increase in the electricity prices. Due to congestion in the transmission network some of the power transactions dispatch may be cancel out. In some cases, Independent system operator tries to alleviate the transmission congestion by real and reactive power rescheduling of generators and in worst cases by curtailment of loads. This paper presents an optimal location of TCSC for reducing the congestion cost in the restructured electricity market. In this paper the most effective generators and loads are selected on the real and reactive transmission congestion distribution factors (TCDFs) values. This paper presents an impact of TCSC on the amount of rescheduling of power and decreasing the congestion cost after placing it optimally in the system. The study has been carried out for pool transactions on 75-bus Indian system.
