In recent years technological advances in power electronics have facilitated the development of electronic equipments that offer the ability to handle large amounts of power; consequently, the use and application of this technology into electrical power systems have increased significantly. These electronic devices, called Flexible AC Transmission System (FACTS), are based on electronic power converters and they provide the ability to make quick adjustments and to control the electrical system. FACTS devices can be connected in series, in parallel, or in a combination of both. The benefits they offer to the electrical grid are widely referenced in scientific literature. These benefits include improvement of the stability of the grid, control of the flow of active and reactive power on the grid, loss minimization, and increased grid efficiency.
