Investigation of the effect of control scheme for the SMES with solid-state phase shifter (SuperSMES) on power system stabilization

The SuperSMES, which is a combination of superconducting magnetic energy storage (SMES) and solid-state phase shifter, is expected to become a new effective apparatus in power systems. This paper shows the results of a new stabilizing control scheme of the SuperSMES for power system stabilization based on experimental results with a 10 kJ superconducting magnet and a 10 kVA model power transmission line. In this paper, the relation between control mode of the SuperSMES for power system stabilization and subsynchronous resonance (SSR) has been also investigated.
