Research on a combined device SMES-SFCL based on multi-object optimization

A multi-function superconducting equipment SMES-SFCL is proposed in this paper. It mainly consists of diodes, power condition system, control circuit and a superconducting coil. Its circuit topology is also presented in the paper. Proved by previous simulation and experiment, the combined device can work as SMES or SFCL separately and effectively. Further research on the performance of the device when it fulfills the two functions simultaneously is proposed in this paper. Control strategy based on multi-object optimization is adopted, which is proved to be applicable by simulation by MATLAB. At the end of the paper, the authors give some suggestion on the device structure and control strategy.
