“…The advantage of toroidal magnets lies in the high magnetic induction intensity during the design of large capacity magnets. Due to the constraint ability of toroidal magnets on magnetic field, the stray field is much smaller than that of solenoid shaped magnets, which can avoid the induction of eddy current loss on the side wall of metal dewar during rapid magnetic flux changes [22]. Therefore, the toroidal magnet was chosen to lay the foundation for a larger scale energy storage magnet design in the paper.…”

The integration of superconducting magnetic energy storage (SMES) into the power grid can achieve the goal of storing energy, improving energy quality, improving energy utilization, and enhancing system stability. The early SMES used low-temperature superconducting magnets cooled by liquid helium immersion, and the complex low-temperature cooling system greatly limited the promotion and application of such devices. SMES based on high temperature superconductivity (HTS) materials can operate in the temperature range of 15–30 K, which simplifies the cooling system and reduces the cooling loss, and greatly improves the operating efficiency and stability of the cooling system. In this paper, the overall design of a 5 MW/10 MJ SMES based on state of the art HTS materials is achieved. The structural parameters of YBCO and MgB2 cables are introduced and the structural parameters of energy storage magnet are analyzed. And the cooling scheme for SMES is provided.

Superconducting magnetic energy storage ( SMES ) systems can store energy in a magnetic field created by a continuous current flowing through a superconducting magnet. Compared to other energy storage systems, SMES systems have a larger power density, fast response time, and long life cycle. Different types of low temperature superconductors ( LTS ) and high temperature superconductors ( HTS ) are compared. A general magnet design methodology, which aims to find the maximum operating current that can be taken by a magnet, is presented. However, for magnets using coated conductors, a more complicated model has to be used because of the shielding currents created by the magnetic field. The Virial theorem is discussed, which limits the maximum energy density in a SMES magnet. The topologies of persistent switch and AC / DC converters have been discussed and compared. In Section 4, an overview of the development history of SMES technologies are discussed. This covers early development of large‐scale SMES for bulk energy storage and recent development of small‐scale SMES for fast‐response applications. Finally, the applications of SMES systems are discussed, which include load leveling, frequency support, and voltage regulations.
