Role of IPFC and SMES for Stability improvement of a Power system with type-2 fuzzy controller

This paper addresses the importance of flexible AC transmission devices for frequency and tie-line power stability improvement of two area power system. The research work has implemented two FACTS devices such as SMES (super magnetic energy storing devices) & IPFC (Interline power flow controller) to improve frequency profile of a non-linear power system. The load dynamic is the main source to create frequency instability issues in the power system. Besides FACTS devices, the paper has also employed a type-2 fuzzy control approach to develop secondary loop in the system. In validity concern, the activity of the suggested type-2 fuzzy controller is compared with type-1 fuzzy controller and PID control approach. The controller parameters are tuned with suggesting a quassi oppositional path finder algorithm (QO-PFA) in different situations. The result and outcomes are obtained through various dynamic responses and numeric values. Finally, it is concluded from the outcomes that FACTS devices having huge effect to improve dynamic performance of the system in different conditions.
