Reactive power compensation in a power distribution network plays a vital role in improving voltage and power system stability. Flexible AC transmission system (FACTS) devices like Static Var Compensators (SVCs) are used to control reactive power generation or absorption in long transmission line. However, these SVCs will introduce harmonic current in to the system due to the operation of thyri...

This paper demonstrates the enhancement of inter-area mode damping by multiple flexible ac transmission systems (FACTS) devices. Power system damping control design is formulated as an output disturbance rejection problem. A decentralized damping control design based on the mixed-sensitivity formulation in the linear matrix inequality (LMI) framework is carried out. A systematic procedure for s...

Deregulation and privatization are posing new challenges to high-voltage transmission systems. High-voltage power electronics, such as HVDC (High Voltage Direct Current) and FACTS (Flexible AC Transmission Systems), provide the necessary features to avoid technical problems in heavily loaded power systems; they increase the transmission capacity and system stability very efficiently and assist ...

Instead of building new substations or transmission lines, proper installation of flexible AC transmission systems (FACTS) devices can make the transmission networks accommodate more power transfers with less expansion cost. In this paper, the problem to maximize power system loadability by optimally installing two types of FACTS devices, namely static var compensator (SVC) and thyristor contro...

<span>The rise in demand for electricity and the high cost of constructing new power networks reckons optimal utilization electric overloading excessive transfer along transmission lines, losses, voltage instability, poor quality, reliability issues. Flexible AC system (FACTS) boosts static dynamic performance systems. Although efficient by improving quality profile enhancement is control...

In present day restructured power systems, increased transactions often lead to the situations where the system no longer remains in secure operating condition. To overcome such undesirable situation the Flexible AC transmission system (FACTS) controllers can be placed in a power system, which are able to provide fast and flexible control of voltage magnitude, active and reactive powers and to ...

The paper presents an apparent impedance calculation procedure for distance relaying of transmission line involving FACTS devices, particularly the UPFC (unified power flow controller). The presence of UPFC significantly affects the trip boundaries which are also adversely affected by fault resistance combined with remote end infeed. Depending on the UPFC location, the trip boundary is influenc...

Deregulation and privatization are posing new challenges to high voltage transmission and distributions systems. System components are loaded up to their thermal limits, and power trading with fast varying load patterns is leading to an increasing congestion. In addition to this, the dramatic global climate developments call for changes in the way electricity is supplied [1, 2]. Innovative solu...

Static Synchronous Series Compensator (SSSC) is a series compensating Flexible AC Transmission System (FACTS) controller for maintaining to the power flow control on a transmission line by injecting a voltage in quadrature with the line current and in series mode with the line. In this work, an Adaptive Network-based Fuzzy Inference System controller (ANFISC) has been proposed for controlling o...
