Flexible AC transmission system (FACTS) is a system composed of static equipments used for ac transmission of electric energy to improve the power transfer capability and to enhance controllability of interconnected network. Unified Power Flow Controller (UPFC) is the most widely used FACTS device for providing fast acting reactive power compensation on high voltage electricity transmission network. This paper deals with the designing of Adaptive Neuro Fuzzy Inference controller (ANFIC) and fuzzy based Particle Swarm Optimization (PSO) controller for the performance analysis of UPFC. The controller have been designed and tested for controlling the real and reactive power of UPFC. Fuzzy-PI controller is used to control the shunt part of UPFC. The system response under high short circuit level is tested on 5-bus system and 118-bus system. Computer simulation by MATLAB/SIMULINK has been used to verify proposed control strategies.

Metrics & MoreArticle RecommendationsT he authors retract this Article due to concerns about the reliability and reproducibility of the published data. On March 31, 2021, a Correction was published related to this Article to correct FTIR and XRD spectra of the reported material presented in Figure 1 and 2 showing identical patterns. However, following the publication of this Correction, additional concerns have been raised. The extensive alteration or misrepresentation of the biochemical studies presented in Figures 7−9 potentially provide misleading conclusions and analysis of experiments, raising significant doubts on the main findings of the work. As such, the Article is being retracted.
