Abstract

This paper describes the use of a STATCOM with Energy Storage System (ESS) to improve the small signal stability of power systems. The ESS considered is a wind farm based Permanent Magnet Synchronous Generator (PMSG) along with an AC/DC converter that is connected to a standard STATCOM. With this configuration of STATCOM/ESS extremely effective control strategies for modulation of reactive and active powers can be devised to improve transient and dynamic stability limits of the system. In this paper this is demonstrated by computer simulation studies on a SMIB model equipped with a STATCOM-ESS combination.
