Congestion management in restructured power system is a major technical challenge for the power system engineers. For a congestion free power market , Available transfer capability(ATC) is to be enhanced. ATC is a measure of remaining MW transaction that can be carried out without violating the transmission limits. In deregulated market , change in load can be met by more than one generator of the system generator participation factor is a measure of amount of power contributed by the generator to satisfy the load.This paper proposes that in simultaneous power transaction generator participation factor can decide the ATC of the network and can also change the maximum amount of load sustained by the bus before causing congestion of the network For this coding is done in MATLB and results are verified on Power world Simulator software

Reliability of network is need of the hour in the present power system market and is constrained by capability of the network. The network calculations are performed using accurate and high efficient strategies. In order to perform power transactions in the system, the computation of available transfer capability is essential which a metric of capability of the system. Generally, effect wattless power is not taken into account in the methodologies for computation of linear available transfer capability. In this paper, a methodology which considers the reactive power flows for enhancement of linear ATC is presented. In order to perform analysis theoretically, a standard IEEE 3 bus system is considered. Another case study i.e., 14 bus system available in IEEE test systems is used for simulation analysis. FACTS technology is incorporated in the existing system in order to enhance capability of the network. To facilitate transfer maximum power in the system, an optimal power-flow-based ATC enhancement model is formulated and presented along with simulation results. Studies based on the IEEE 3-bus system and 14-bus systems with TCSC demonstrate the effectiveness of FACTS control on ATC enhancement.
