This paper introduces the first moveable conduction-cooled high temperature superconducting magnetic energy storage system (M-SMES) made in China. The M-SMES is rated at 380 V/35 kJ/7 kW, consisting of the high temperature magnet confined in the dewar, the cryogenic unit, the converter, the monitoring and control unit, and the container, etc. The proposed M-SMES can be loaded to a truck to transport to the desired place and put into use through easy connection. The laboratory and field test results were given. Test results indicate that the M-SMES is fimctioned with energy storage, featuring with fast response to four-quadrant power regulation. The accessories for moveable feature and anti-shock property are well designed. The M-SMES performs well during the field test. The power oscillation is damped and bus voltage is improved. It is feasible to be put into utility in the future power system.
