1 Introduction Transmission systems of present power network are reliably crashed into increasingly focused on level because of the ascent in load requests and limitations of developing new lines. The result of such an accentuated framework would be gaining instability trailed by interference because of a fault. Use of FACTS devices has ended up being an exceptionally viable strategy to cut down the pressure of the power system grid and consequently issues in better usage of concerned accessories in power framework without bargaining the appropriate margin of stability [1]. Position of FACTS controllers play a crucial role in congestion management, and FACTS controllers used for the problem of reactive power compensation can be solved. Flexible AC transmission system (FACTS) was first brought into light by Hingorani [2] in 1988. Power flow control method has been presented by Gothana and Heydt [3]. A brief search for the optimal position of FACTS controllers is discussed by Lie and Dang [4]. This paper deals with improvement in operational performance of power system using UPFC FACTS devices. The simulation is executed using PSAT in the MATLAB. The area for the situation of UPFC is purposefully utilising an index termed as network branch index (NBI) [5]. Voltage stability improvement is assessed by extension power flow method present in [6]. UPFC is used with the optimal variables which are reducing L. Kumar · K. Verma (B) · S.

the real power loss and the system running cost [7]. Various optimization methods are explained in [8]. Increase in the loadability with FACTS devices is described in [9]. In [10], author describes the reactive power compensation. In this paper, voltage crash point using the load flow jacobian matrix is presented [11]. The authors in [12] presents gravitational search algorithm (GSA)-based enhancement strategy for the ideal coordination of FACTS controller with the current imaginary power sources present in an associated power grid. Basic principle of the UPFC is described in [13]. Power system analysis toolbox (PSAT) gives graphical consolidate of power flow analysis, and PSAT toolbox detects the most precise node [14]. In this paper, [15] shows how to the improve voltage stability using shunt devices. All the parameters are concluded for voltage collapse using the PSAT MATLAB and description of weak node with the help of voltage stability index [16].
