FACTS (Flexible AC Transmission System)

FACTS (Flexible AC Transmission Systems) are advanced technology devices used in power grids to improve the flow and stability of electricity. They help control and optimize the transmission of alternating current (AC) power by adjusting voltage, phase angle, and power flow in real-time. This increases the capacity, reliability, and efficiency of the electrical network, reduces losses, and helps manage load fluctuations. Essentially, FACTS devices act like intelligent controllers that enhance the performance of the power system, making the delivery of electricity more stable, flexible, and efficient across long distances and complex grids.
