Fast acting energy storage devices can effectively damp electromechanica l oscilla­ tions in a power system, because they provide storage capacity in addition to the kinetic energy of the generator rotor, which can share the sudden changes in power requirement. The present paper shows the effectiveness of small sized magnetic energy storage (MES) units (both superconducting and normal loss types) for this application and suggests means of best utilization of the small energy storage capacity of such units to improve the load­ frequency dynamics of large power areas.
