Abstract
A hybrid HTS SMES using two different kinds of superconducting coils, BSCCO and YBCO coil, is optimized to achieve the maximum energy storage taking the influence of the magnetic field into account. The cooling system with sub-cooled LN2 maintains the cryogenic operating environment at 69K. A LCL filtered voltage source power converter (VSC) is designed for the HTS SMES. A dual processor combined with DSP and MCU is applied in the dual-core controller and a digital closed loop algorithm based on the SVPWM pulse modulation is programmed for the VSC-based SMES. The dynamic simulation experiment is achieved with the hybrid HTS-SMES in different scenarios for the power fluctuation compensation. The experimental results validate that the SMES can output the required compensation power and restrain the power fluctuation in milliseconds.
