This paper presents the load-flow modeling and steady-state capabilities of the bundle-controlled line impedance modulator (LIM). This distributed flexible ac transmission system device is under development for the management of power flows. In particular, this paper presents the back-to-back interconnection of two bundle-controlled line segments. The LIM configuration is very interesting from an economic and operational point of view: it enables continuous control of the transmission-line impedance from its standard value up to 1.64 p.u. and, as a result, the power flow can be reduced smoothly. Index Terms-Bundle conductors, flexible ac transmission systems (FACTS), line impedance modulator (LIM), load-flow control, power system simulation, power transmission lines.

“…OPF with ABC for setting of SVC was presented in [80] for system bus voltage profile improvement. [18,29,81]. Active power loss minimization was achieved with the incorporation of TCSC, SVC and UPFC into IEEE 30 bus network in the work presented by [81] with the observation that loss control led to reduction and operational cost.…”

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 DPFC placement strategy may not be unique after being optimized in this stage. The reason is that the installation cost coefficients of each line are assumed to be equal in (21). Therefore, a unique DPFC placement can be obtained by adopting differentiated coefficients according to the actual situation.…”

“…Compared with the lumped FACTS devices, little effort has been devoted to the configuration of D-FACTS devices. In [21], the optimal placement of DSSCs is presented by investigating the sensitivity of real power loss with respect to line impedance. However, this method, which decouples the location and capacity of devices, cannot always achieve the optimal objective.…”

Increasing energy consumption has caused power systems to operate close to the limit of their capacity. The distributed power flow controller (DPFC), as a new member of distributed flexible AC transmission systems, is introduced to remove this barrier. This paper proposes an optimal DPFC configuration method to enhance system loadability considering economic performance based on mixed integer linear programming. The conflicting behavior of system loadability and DPFC investment is analyzed and optimal solutions are calculated. Thereafter, the fuzzy decision-making method is implemented for determining the most preferred solution. In the most preferred solution obtained, the investment of DPFCs is minimized to find the optimal number, locations and set points. Simulation results on the IEEE-RTS79 system demonstrate that the proposed method is effective and reasonable.
