Poonam Singhal, S. K. Agarwal and Narender Kumar

To control the power flow, for increasing the transmission capacity & for power system stability, FACT devices are used. Unified Power Flow Controller is most widely used. This paper presents a novel Bacterial foraging technique (BFO) for optimizing the PI controller parameters of UPFC for the transient stability enhancement of SMIB system. Complete modeling is done for SMIB system with UPFC controller. PI controller parameters computed by conventional method [23] are usedas base for BFO, Bacterial Foraging Optimization Technique is applied for computing better optimized values. Results exhibit that BFO technique is able to find a better quality solution as compared to conventional technique for the proposed problem.
