The integration of an energy storage system, such as battery energy storage
(BESS), into a FACTS device can provide dynamic decentralized active power
capabilities and much needed flexibility for mitigating transmission level
power flow problems. This paper will introduce an integrated StatCom/BESS
for the improvement of dynamic and transient stability and transmission cap
ability; compare the performance of the different FACTS/BESS combinations,
and provide experimental verification of the proposed controls on a scaled
StatCom/BESS system.
