The Flexible Alternative Current Transmission System and Distribution Flexible AC Transmission System (FACTS/DFACTS) are a new converging technology based on the Power Electronics, Control Theory, and Power System for the revolution of ever more efficient control and better utilization of power and energy in the existing systems. The FACTS offers an opportunity to enhance the controllability, stability, and power transfer capability of AC transmission systems with the fastest control speed. DFACTS is the extended modern technique of FACTS to focus on the Custom issues or power line conditioning in the distribution site as well as the Information Technology's Electricity Issues.

CILO-1: Explain the basic concepts, fundamental operational principles, advantages and disadvantages of different FACTS/DFACTS devices. CILO-2: Identify the control strategies of some selected Flexible Alternative Current Transmission System and Distribution Flexible AC Transmission System.
