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

We studied the feasibility of a cryocooler cooled 15 kWh HTS-SMES for syste m stabilization, HTS magnets will have better properties at high magnetic f ield than do LTS magnets, the volumes of HTS magnets are expected to be red uced. In the study, we calculated volumes, flux-flow losses and ac losses o f 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 kWh HTS-SMES magnet designs.
