This document summarizes research on using SSSC (Static Synchronous Series Compensator) and STATCOM (Static Synchronous Compensator) to improve power quality and voltage stability in a two machine, four bus power system model. It describes the basic operational principles of SSSC and STATCOM, which are FACTS devices that can be connected in series and parallel, respectively, with transmission lines. The document presents simulation results showing that connecting an SSSC to Bus 2 and a STATCOM to Bus 2 both increase the voltage levels and regulate active and reactive power flows at the different buses, demonstrating the effectiveness of these devices for maintaining voltage stability.
