Fuzzy logic damping controller for FACTS devices in interconnected power systems [PDF]

open access: yes, 1999
Fuzzy controllers are designed for flexible AC transmission systems (FACTS) in interconnected power systems. Two typical FACTS devices, a static synchronous compensator (STATCOM) and a unified power flow controller (UPFC), are used as examples to show ...
