Abstract
In this paper, a sensitivity based approach is proposed for optimal allocation of optimal unified power flow controller (OUPFC) under single line contingency to eliminate overloads on transmission lines. The approach is formulated based on ranking index (RI) and performance index (PI). After outage of a branch element, a unitary variation of power flow (PF) in every transmission line is attained through RI. It is formulated to quantify loading level of network after a given outage. Contingencies are organized in descending order depending on the value of RI. Sensitivity factors are attained by differentiating real power flow performance index (RPFPI) subjected to system parameters of OUPFC. Optimal allocation of OUPFC is based on sensitivity factors obtained by considering line outages in the order of their severities which is given by RI. The proposed approach is programmed on 5-bus and IEEE 14-bus networks under MATLAB environment.
