This research proposes a differential analysis for determining the suitable location for FACTS devices (TCSC) and TCPAR to enhance network security during single-line outages (N-1). To ensure optimal device deployment when dealing with sensitivity variables, the proposed technique is based on performance index (PI) and ranking index (RI). The severity of the line in the network is ranked by the contingency case. The system loading level for a specific outage is computed using RI. Differentiating the proposed performance index (PI) applied to system parameters of TCSC and TCPAR yields sensitivity factors. The sensitivity factors determined by RI are utilized to determine best placement of TCSC and TCPAR devices. The goal of this problem is to reduce line overloads on transmission lines in the event of a network outage. The proposed technique is tested in a MATLAB environment on IEEE 5 bus and 14 bus networks.

This paper presents Sensitivity constrained placement of unified power flow controller (UPFC) considering active-power flow sensitive index (APFSI) and static voltage stability index (STATIC-VSI) to minimize active-power losses and to improve power transmission capacity. The sensitive factors are derived with respect to voltage, phase angle and current to formulate APFSI. Transmission line impedance parameters along with active and reactivepower flow measurements are considered to formulate static-VSI. Sensitivity constrained differential evolutionary (SCDE) algorithm is proposed for parameter setting through which power control and minimization of losses in system can be achieved. Testing is performed on IEEE-5, 14 and 30-bus networks in MATLAB and results indicate that SCDE is robust optimization technique compared to conventional method and genetic algorithm (GA)
