Mitigation of congestion in transmission line using series smart wire

Abstract

In the deregulated power system market, congestion management is one of significant technical issues. Congestion management demands for decrease in load in a particular line, installation of flexible AC transmission system (FACTS) devices in transmission line for reliability and the addition of new renewable generation unit. Various new technologies have been developed so far to mitigate congestion within the network without construction of any new line. This paper presents an idea of mitigating congestion by using Smart Wire (SW) in series. SW series module operates whenever congestion is detected and during normal condition, the smart wire circuitry is bypassed. This technology supports the efficacy of the system by decreasing relevant losses also. Proposed system utilises 15 bus IEEE system in MATLAB/Simulink to demonstrate the working of smart wire, and the results are formulated graphically.
