This paper presents a novel method for optimal location of FACTS controllers in a multi machine power system using Genetic Algorithm(GA). Using the proposed method, the location of FACTS controller, their type and rated values are optimized simultaneously. Among the various FACTS controllers, Thyristor Controlled Series Compensator (TCSC) and Unified power Flow Controller (UPFC) are considered....

The characteristics of the distance relay are devised based on online and fault impedance. uses information to react expected state; however, integrating grid with a unified power flow controller (UPFC) might stop from fault-triggered operations, requiring altered characteristics. Building tripping parameters among critical challenges that must be addressed for transmission line relays because ...

Optimal power flow (OPF) study is conducted on a power system to achieve one of the following objectives: cost/loss minimization or available transfer capability (ATC) calculation in a deregulated environment. Distributed generation (DG) is a small source of electric power conversion from nonconventional energy sources and Hybrid DGs which often the most cost-effective and reliable way to produ...

<span lang="EN-GB">The doubly-fed induction generator (DFIG) based wind farm is widely used for extracting energy from the wind. When connected to grid, generally it causes some perturbations. It can disturb function of grid and installations grid. This impact concerns load flow, voltage drops, frequency fluctuations. To overcome those issues, unified power flow controller (UPFC) recommen...

This paper describes and validates transient stability and power flow model of a Unified Power Flow Controller (UPFC), and presents a detailed comparison of different controls strategies, proposing novel, efficient and simple controls for this controller. The proposed model accurately represents the behavior of the controller in quasi-steady state operating conditions, and hence is adequate for...

Abstract—Weak damping of low frequency oscillations is a frequent phenomenon in electrical power systems. These frequencies can be damped by power system stabilizers. Unified power flow controller (UPFC), as one of the most important FACTS devices, can be applied to increase the damping of power system oscillations and the more effect of this controller on increasing the damping of oscillations...
