This project's primary goal is to reduce power losses and improve voltage profiles in power networks by strategically using unified power flow controllers, or UPFCs. The optimization process is enhanced by the combination of Fuzzy Logic and Archimedes Optimization Algorithm (AOA) techniques. The current injection model has been used to optimize the sizing of the Unified Power Flow Controller (UPFC) by the application of the Archimedes optimization method. The suggested approach demonstrates how simple it is to manipulate ideal power flow assessments. Fuzzy systems are used to compute the voltages and power loss at the best places. This paper is a demonstration of how to reduce power loss and enhance voltage under different load scenarios, such as light load, normal load, and overloading cases. It also shows how to apply UPFC to improve system performance on IEE-14 and IEE-30 bus systems.
