FACTS technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. STATCOM is oneof the most important FACTS devices used in the parallel compensation, enhancing transient stability andetc. Since three phase fault is widespread in power systems, in this paper STATCOM is used...

Power system is subjected to sudden changes in load levels. Stability is an important concept which determines the stable operation of power system. In general rotor angle stability is taken as index, but the concept of transient stability, which is the function of operating condition and disturbances deals with the ability of the system to remain intact after being subjected to abnormal deviat...

This paper proposes two new methodologies for the placement of series FACTS devices in deregulated electricity market to reduce congestion. imilar to sensitivity factor based method, the proposed methods form a priority list that reduces the solution space. The proposed methodologies are ased on the use of LMP differences and congestion rent, respectively. The methods are computationally effici...

Congestion and overloading for lines are the main problems in the exploitation of power grids. The consequences of these problems in deregulated systems can be mentioned as sudden jumps in prices in some parts of the power system, lead to an increase in market power and reduction of competition in it. FACTS devices are efficient, powerful and economical tools in controlling power flows through ...

This paper presents an enhanced Genetic Algorithm (EGA) based approach to solve the Optimal Power Flow (OPF) with FACTS devices to eliminate line over loads in the system following single line outages. The optimizations are performed on two parameters: the location of the devices, and their values. Two different kinds of FACTS controllers are used for steady state studies: Thyristor Controlled ...

In this paper, a security constrained optimal power flow (SCOPF) is developed including the flexible AC transmission systems (FACTS) devices for the economic and secure operation of power systems. FACTS devices are used to control the active and reactive power variables as well as the voltages and to reduce the flow of a congested line. In this paper, Thyristor Controlled Series Capacitor (TCSC...

This paper presents a study on optimal location and sizing of multiple FACTS devices based on Particle Swarm Optimization (PSO) for minimization of transmission losses, and voltage profile improvement, which takes into account the cost of installation. In this study, Static Var Compensator (SVC) and Thyristor Controlled Series Compensator (TCSC) are chosen as the compensating device for the pur...

In the present day world power system deregulation is at its full stretch. In this deregulated environment ensuring that the power system operates with in its specified limits, which have been traditionally referred to as power system security is the most concerned aspect, which is currently being given at most importance. The term reliability depends on transmission loss. Maintaining the secur...

This paper presents, “Performance Analysis of power flow control through FACTS Devices in Power System. In a power system network consisting of generators, transmission lines, transformers and load etc., STATCOM, SVC and UPFC are applied between two buses separately and their effects are analyzed as par applied system conditions. Power flow between different buses and voltage regulation of abov...

Wind generation connection to power system affects steady state and transient stability. Furthermore, this effect increases with the increase of wind penetration in generation capacity. In this paper, optimal location of FACTS devices is carried out to solve the steady state problems of wind penetration using Genetic Algorithm (GA).
