The integration of an energy storage system into FACTS devices may lead to a more economical and/or flexible transmission controller. Various energy storage systems have received considerable attention in power utility applications due to their characteristics that range from rapid response, high power, high efficiency, and four-quadrant control. The enhanced performance of combined FACTS/ESS may have greater appeal to transmission service providers. Integrating an energy storage system into a FACTS device can provide dynamic decentralized active power capabilities and much needed flexibility for mitigating transmission level power flow problems. This paper presents a comprehensive comparison between the dynamic performances of a StatCom, a StatComBESS, an SSSC, an SSSC/ESS and a UPFC.
