An Energy Storage System (ESS) installed in a power system can effectively damp power system oscillations through controlling exchange of either active or reactive power between the ESS and power system. This paper investigates the robustness of damping control implemented by the ESS to the variations of power system operating conditions. It proposes a new analytical method based on the well-known...
This is the second part of the paper, presenting results of simulation tests of an example power system installed with a STATCOM-based stabilizer. Extension to more complicated case of multi-machine power systems is also discussed in this part.
STATCOM (static synchronous compensator) and SSSC (series static synchronous compensator) are two new generation of FACTS devices based on voltage source converter (VSC). In this paper, a novel analytical method based on the well-know equal-area criterion in studying their capability to improve power system oscillation stability is proposed and some useful analytical conclusions are presented. Simulation...
