Abstract: This study investigates the effects of applying Static Synchronous Compensator (STATCOM) to electric power systems with losses. The northeast and part of northwest of the Nigerian grid system is chosen for a case study in order to characterize the performance of the entire power systems and infer at what point or under what condition, the system can suffer from emergency voltage instability. The intent is to examine whether such FACTS (Flexible AC Transmission System) device can be effective in minimizing the transmission losses and improve the voltage stability. Simulation results carried out in the PSCAD/EMTDC environment are presented to show the significant reduction of power losses in transmission lines and improvement of voltage stability with STATCOM.
