This paper discusses the integration of a static synchronous compensator (STATCOM) with an energy storage system in damping power oscillations. The performance of the STATCOM, a self-commutated solid-state voltage inverter, can be improved with the addition of energy storage. In this study, a 100 MJ SMES coil is connected to the voltage source inverter front-end of a STATCOM via a DC-DC chopper. The dynamics of real and reactive power responses of the integrated system to system oscillations are studied using an electromagnetic transient program PSCAD TM /EMTDC TM and the findings are presented. The results show that, depending on the location of the STATCOM-SMES combination, simultaneous modulation of real and reactive power can significantly improve the performance of the combined compensator. The paper also discusses some of the control aspects in the integrated system.
