Power transmission lines congestion control with proper placement of smart wire

Abstract

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.
