Abstract A kJ class high temperature superconducting magnetic energy storage system (HT-SMES) composed of first generation (BSCCO) and second generation (YBCO) HTS wires with sub-cooled LN2 cooling system was optimal designed and applied for the power fluctuation compensation in power system. A dual processor combined with the digital signal processor (DSP) and the micro-programmed control unit (MCU) was proposed and used in the LCL filtered voltage source converter for the hybrid SMES. Based on the SVPWM the power fluctuation compensation strategy of the SMES and its program realization based on the code composer studio (CCS) were given for achieving the dynamic monitoring and compensation strategy calculation in power system. Finally, a dynamic simulation test system with this SMES and a 200km length transmission line for compensation the power fluctuation was build up. The experimental results show that the SMES can output the required compensation electric power and restrain the power fluctuation in millisecond, which validate the effectiveness of the SMES converter and the control strategy as well.

Key words： High temperature superconducting magnetic energy storage system BSCCO YBCO dynamic simulation test power fluctuation compensation.
