Abstract: The global demand for electricity is steadily increasing, driven by industrialization, population growth, and the increasing adoption of electric vehicles and other energy-intensive technologies [1,2].Meeting this demand while ensuring reliable and high-quality power supply is a major challenge for power system operators [3].Traditional power grids, often designed for centralized generation and unidirectional power flow, are struggling to cope with the increasing complexity and variability of modern power systems [4].One of the primary challenges is the integration of renewable energy sources (RES), such as solar and wind power, into the grid [5,6]. *Author for correspondenceWhile RES offer significant environmental benefits, their intermittent nature poses challenges for grid stability and power quality [7,8].Furthermore, the increasing demand for power necessitates efficient and reliable transmission of electricity over long distances, often through aging infrastructure [9,10].To address these challenges, flexible alternating current (AC) transmission systems (FACTS) devices have emerged as a crucial technology for enhancing power system controllability and reliability [11,12].FACTS devices utilize power electronics to dynamically control power flow, voltage, and other critical parameters, enabling improved power quality, stability, and overall grid performance [13,14].Among various FACTS devices, the unified power flow controller (UPFC) stands out as a highly versatile and powerful solution [15,16].The UPFC,
