Abstract: |
In this paper, a battery energy storage system
(BESS) based control method is proposed to improve the
damping ratio of a target oscillation mode to a desired level
by charging or discharging the installed BESS using local
measurements. The expected damping improvement by
BESS is derived analytically for both a single-machineinfinite-bus
system and a multi-machine system. This
BESS-based approach is tested on a four-generator, twoarea
power system. Effects of the power converter limit,
response time delay, power system stabilizers and battery
state-of-charge on the control performance are also investigated.
Simulation results validate the effectiveness of the
proposed approach. |
