Flexible alternating current transmission systems (FACTS) deployments and applications are on the increase in modern day power network systems because of their advantages over conventional ways of power network physical expansion. Therefore, a comprehensive review of FACTS controllers with their various applications is carried out in this paper. Formation of different applications and advantages of FACTS devices into voltage control, power flow control, system stability control, power quality control, and economic benefits as inferred from the literatures is among the vantage points of this presentation. FACTS background alongside different techniques of deployments, leading to various applications and performance of these devices, hitherto organized structurally based on target objectives are also explored, presented and discussed. Summarily, this study provides an overview of the background, topological structures, deployment techniques and cutting-edge utilization of FACTS controllers, with a view to acquainting power players, electrical engineers, network designers as well as researchers, with the trends in the development, status and future direction of FACTS applications. Convincingly, the content of this article will benefit all the stakeholders in the area of FACTS deployments and utilizations.

“…The Flexible Alternating Current Transmission System (FACTS) has become the head of concern of the modern powers where the FACTS can change the parameters of the power system such as the transmission line impedance, the magnitude and the phase angle of the buses voltage and the power flow in the network. Consequently, the FACTS are widely used to enhancing the technical and economic issues related to the power system operation including enhancing the system stability, the loadability, the security, minimizing the power losses and system generation cost [1,2]. The FACTS controllers are power electronic devices, from this prospective FACTS can be classified into two types as depicted in Figure 1: (1) The variable impedance type and (2) The Voltage Source Converter (VSC) type [3].…”

It should be point out here that the FACTS controllers based VSC have high control ability compared with the variable impedance FACTS where the FACTS controllers based VSC can inject AC voltage with controllable voltage magnitude and phase angles to system.…”

The Optimal Unified Power Flow Controller (OUPFC) is an efficient series-shunt controller that is incorporated to system to control the power flow through the transmission lines. Modeling of such controller is a challenge task due the required complex modifications of the Newton Raphson power (NR) flow to consider the parameters of the OUPFC. The aim of this paper includes (1) presenting an efficient novel model of the OUPFC into NR power flow, (2) avoiding the complicities of modeling the parameters of the OUPFC into power flow solution, (3) multi-control modes of the OUPFC is established to control the active and reactive powers concurrently or separately and, (4) handling the violation of the operating constraints by using developed methods. The proposed model is based on the power injection representation where the parameters of the OUPFC are represented as injected loads as a function of the pre-requested control variables (specified values). Therefore, the complicities of including its parameters are reduced. The developed methods for handling the violations of the operating constraints are based on modifying the specified values as a function of the maximum limits of the operating constraints. The proposed OUPFC model and the developed constraints handling methods are implemented on IEEE 14-bus, IEEE 30-bus, IEEE 57-bus and IEEE 118-bus test systems. The simulation results verified the feasibility and robustness of the presented model into load flow analysis. in addition, effectiveness of the proposed approaches for handling the operating constraints of OUPFC.INDEX TERMS Power Flow, FACTS, Optimal Unified Power Flow Controller, The operating constraints. .

El subsistema de transmisión en sistemas eléctrico de potencia es muy importante, debido a que es el encargado de llevar la energía eléctrica desde la generación hasta la etapa de subtransmisión y posteriormente a ser distribuida. Las aplicaciones de los FACTS SVC en las barras del sistema eléctrico de potencia son variadas; estos dispositivos nos permiten modificar el flujo de potencia en el sistema de potencia, con el fin de aprovechar al máximo la capacidad de las líneas de transmisión; el ubicar estos elementos compensadores de potencia reactiva tiene un costo elevado, por lo que es necesario ubicarlos de forma óptima e inteligente, con el fin de hacer que la inversión sea factible. En la presente investigación se presenta una metodología para minimizar la desviación de las magnitudes de los perfiles de voltaje, para lo cual analizamos el comportamiento antes y después de la compensación reactiva en redes de transmisión mediante programación no lineal considerando ubicación óptima de SVC en los modelos de 14 y 30 barras del IEEE (Institute of Electrical and Electronics Engineers). Finalmente, la ubicación de compensadores de potencia reactiva en las barras del SEP mejora los perfiles de voltaje en cada una de sus barras, minimiza costos de inversión y reduce las pérdidas de potencia activa y reactiva en las líneas de transmisión.
