| Abstract |
This paper presents a placement method of fuzzy logic based unified power flow controller (UPFC) inpower system network by analyzing dynamic voltage stability. Voltage stability indices namely LQPand voltage collapse point indicators (VCPI) indices are used to determine the weakest line for UPFCby dynamic load variation. The controllers of the shunt and series converters of the UPFC aredeveloped using fuzzy logic (FL) and proportional integral (PI) controllers respectively to enhance thedynamic voltage stability of the power system network.The simulation has been conducted in powersystem computer-aided design (PSCAD) environment where IEEE-5 and IEEE-14 bus system havebeen chosen as test bench systems. The results obtained through simulations have ensured theeffectiveness of the proposed placement method since fuzzy based UPFCs placement in the obtainedlocations resulted in significant improvment in voltage stability. |
