Abstract
AbstractFlexible Alternating current Transmission Systems (FACTS) devices are very essential in power system analysis and in transferring high-quality power. FACTS devices are used for controlling the voltage stability, improving power flow, and security of transmission lines. There are different types of facts devices depending on their application on the power system network which includes SVC, TCSC, SSSC, STATCOM, and UPFC. However, it is necessary to find the optimal location and sizing for these devices in power networks. The spiral dynamic algorithm is a recently developed optimization technique that can be used widely in power systems. This study presents an approach to finding the optimal location and sizing of a unified power flow controller (UPFC) device in a power network using the spiral dynamic algorithm technique. This technique is based on natural spiral patterns such as tornadoes, hurricanes, and galaxies. In this study, the enhancement of voltage profile, power loss reduction, and increase of load-ability is carried out using UPFC. The work was implemented in MATLAB 2019b environment. Power network parameters were defined and tested in the IEEE 30-bus and 54-bus Nigerian Network. The real and reactive power loss of the 30 Bus network withoutwith UPFC were found to be 17.528MW68.888Mvar and 7.461MW33.989Mvar with a percentage reduction of 57.43%50.66%, while the 54-bus Nigerian Network recorded 28.427MW30.744Mvar and 14.962MW20.496Mvar with a loss percentage reduction of 47.37% and 33.33% respectively.Keywords: FACTS, Sizing, UPFC, SDA, Nigerian 330kV Power Network.
