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.

In this article, Interline power flow controller (IPFC) has been recommended to limit the short circuit current (SCC) in low voltage (LV) electrical distribution system. Industrial loads are increasing due to various reasons in the distribution system. It leads to the power requirement at the distribution system level. Therefore, there is a scope for increase in the fault current. Due to the increased fault current, the protection of switchgear is vital. A simple control strategy wth IPFC is proposed in the distribution system to limit the fault current. Low voltage distribution system i.e 800 MW thermal power plant water system LV distribution system is considered for demonstrating the effectiveness of the IPFC. Short circuit analysis is performed without and with the IPFC by applying ETAP and MATLAB (SIMULINK). The simulation results are compared. Further, the effect of different ratings of standard transformers is also analyzed. It is noticed that the control strategy with IPFC can limit the fault current.
