Improving distribution system performance with integrated STATCOM and supercapacitor energy storage system
Zhengping Xi,Babak Parkhideh,Subhashish Bhattacharya +2 more
- 15 Jun 2008
TL;DR: In this article, the integration and control of energy storage systems (ESSs), such as supercapacitor (ultracapacitor - UCAP) into a D-STATCOM (Distribution system STATCOM) is developed to mitigate such problems, enhance power quality and improve distribution system reliability.

STATCOM Operation Strategy under Power System Faults
Zhengping Xi,Subhashish Bhattacharya +1 more
- 24 Jun 2007
TL;DR: In this paper, an emergency PWM strategy was proposed to prevent overcurrents in the VSC during and after system faults, with slightly different B-H characteristics for series connected transformers.

STATCOM Control and Operation with Series Connected Transformer Based 48-pulse VSC
Zhengping Xi,Subhashish Bhattacharya +1 more
- 01 Nov 2007
TL;DR: The STATCOM control and operation for a 48-pulse VSC topology implemented with series connected transformers is reported and the control scheme for the STATCOM is fully validated by detailed simulations for a 2-bus power system.
