Research and development of superconducting magnetic energy storage system: Feasibility study of a cryocooler cooled 15 kWh HTS-SMES

Abstract We studied the feasibility of a cryocooler cooled 15 kW h HTS-SMES for system stabilization. HTS magnets will have better properties at high magnetic field than do LTS magnets, the volumes of HTS magnets are expected to be reduced. In the study, we calculated volumes, flux-flow losses and ac losses of various shapes of the HTS magnets at a settled load factor and found that more than 10 T of maximum applied field to the magnets should be selected for the cryocooler cooled 15 kW h HTS-SMES magnet designs.
