摘要: Transient and dynamic stability considerations are among the most important issues in reliable efficient operation of power systems. Flexible AC Transmission Systems (FACTS) devices produced more flexibility system control, thus improving usage existing transmission A unified flow controller (UPFC) has ability to adjust three control parameters, viz. bus voltage, line reactance, phases angle between two buses either simultaneously or independently. In this paper, a small population based particle swam optimization (SPPSO) is used optimally tune parameters UPFC multi-machine system, providing faster convergence less computation time. Simulation results on Nigerian grid modeled PSAT environment with without installed were presented. The revealed appreciable enhancement voltage profile, along lines damping oscillations.
