STATCOM/Ultracapacitors

Abstract

"Flexible AC Transmission System (FACTS) topologies are designed for the decentralized control of bulk transmission power flow. Integrating an energy storage system (ESS) into FACTS devices can provide additional flexibility to stabilize the transmission system. In this thesis, an ultracapacitor (UCAP) is introduced into the STATCOM as a potential replacement for traditional energy storage systems. This thesis provides experimental validation of the STATCOM/UCAP response and compares it to a STATCOM with battery energy storage.

Moreover, a thirteen-level cascaded multilevel converter-based ST ATCOM with carrier phase-shifted SPWM (CPS-SPWM) control has been developed and integrated into a power system. The dynamic response of the 13-level STATCOM with and without the UCAPS is then analyzed. The dc link voltage balancing problem is ·addressed by introducing redundant state selections (RSS) to control the charge and discharge of the capacitors to better balance the capacitor voltages"--Abstract, page iii.
