مدل سازی کنترل پویا و شبیه سازی یک جبران UPFC-SMES در سیستم های قدرت

Flexible AC Transmission Systems (FACTS) is granting a new group of advanced power electronic devices emerging for the enhancement of the power system performance. Unified Power Flow Controller (UPFC) is a recent version of FACTS devices for power system applications. The back-up energy supply system incorporated with UPFC is providing a complete control of real and reactive power at the same time and hence is competent to improve the performance of an electrical power system. In this article, backup energy supply units such as superconducting magnetic energy storage (SMES) are integrated with UPFC. In addition, comparative exploration of UPFC–battery, UPFC–UC and UPFC–SMES performance is evaluated through the vibrant simulation by using MATLAB/Simulink software.
