Evaluation of Flexible AC Transmission System (FACTS) technologies on the Tennessee Valley Authority`s transmission system

This report evaluated the potential for applying Flexible AC Transmission System (FACTS) controllers on the Tennessee Valley Authority (TVA) system. Part A of this report describes the potential voltage collapse resulting from a loss of the West Point transformer, as well as potential solutions. an economic evaluation was performed to provide a comparison between the various conventional, FACTS and hybrid solutions. Part B of the report describes the potential application of FACTS controllers, specifically static synchronous condensers, to loss-of-infeed problems. This section also includes an economic evaluation that compares the various solutions. Part C of this final report describes methods to increase the interchange capability of the TVA system.
