Power quality issues such as voltage instability, increased real and reactive power losses, and poor voltage profile have become critical challenges in modern interconnected power systems due to growing load demand and the integration of nonlinear loads. Flexible AC Transmission System (FACTS) devices provide an effective solution for dynamic reactive power compensation and voltage regulation. This paper presents a comparative analysis of two shunt FACTS devices, namely Static VAR Compensator (SVC) and Static Synchronous Compensator (STATCOM), for enhancing voltage profile and minimizing transmission losses using an Optimal Power Flow (OPF) approach. The IEEE-14 bus system is considered as a test system. Simulation results demonstrate that optimal placement and sizing of STATCOM yields superior performance compared to SVC in terms of real and reactive power loss reduction and voltage profile enhancement.
