A Review on Optimal Location and Parameter Settings of FACTS Devices in Power Systems Era: Models, Methods

Flexible Alternating Current Transmission Systems (FACTS) devices have been proposed as an effective solution for controlling power flow and regulating bus voltages in electrical power systems, resulting low system losses, and improved stability. Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages in desired level. The FACTS devices placement problem is commonly solved using heuristic optimization techniques which are diverse and have been the subject of ongoing enhancements. This paper presents a survey of the literature from the last decade that has focused on the various techniques applied to determine optimal location of FACTS devices. Several models and methods have been suggested for the optimal location and parameter setting of FACTS devices. This paper presents an overview of the state of the art models and methods applied to the power system problems, analyzing and classifying current trends in this field
