-Transmission congestion results from the contingencies in the power system and increasing load demand that has to be supplied through predetermined corridors in case of restructured environment. The Flexible AC Transmission Systems (FACTS) devices when deployed in a power system can result in improving the system performance in terms increased loading capability of transmission lines, reduction in losses, improved stability and security of the system by relieving stress on congested lines. This work deals with congestion management of the power transmission network by employing FACTS devices, with the help of Genetic Algorithm (GA) based optimization algorithm. Optimal location of FACTS placement and optimal parameter settings of these devices are the objectives for the optimization problem. The optimization process aims at maximizing the loading capability by the network by transferring power from overloaded lines to adjacent lightly loaded lines. FACTS devices considered are TCSC, SVC and UPFC for the alleviation of the overload on transmission lines and to reduce overall transmission loss of the system. An IEEE 30-bus system is used to illustrate the effectiveness of the proposed method.

Congestion is severe problem that affects the power system security as it violates the various operating limits of the power system so congestion management is an important task for independent system operator. For managing congestion, smart wire module has been used in series with transmission line. When smart wire is connected in series with most congested line, there is improvement in voltage profile, reduction in transmission line loading and losses. Transmission Congestion Distribution Factor (TCDF) is calculated to know congestion in lines and congestion is managed with the help of smart wire module. It is observed that value of TCDF also reduced when smart wire is connected. Work has been carried out on IEEE 15 bus system on MATLAB.
