Abstract

Superconducting magnets are crucial components of superconducting magnetic energy storage (SMES) systems, directly impacting the economic efficiency and stability of energy storage systems. This study focuses on a hybrid toroidal magnet of 10 MJ HTS SMES system with D-shaped coils, aiming to optimize its design by minimizing the cost of superconducting conductors. An improved particle swarm optimization (IPSO) algorithm is employed, which integrates chaotic mapping and introduces crossover and mutation operators based on the Metropolis criterion. Factors such as the magnet’s critical current, minimum bending radius of superconducting cables, and safety margin are considered during the optimization process. Comparative analysis demonstrates that the IPSO algorithm outperforms the standard PSO algorithm in terms of convergence speed and accuracy. Finally, an optimized design scheme for the hybrid toroidal magnet of a 10 MJ HTS SMES system is presented. This paper provides optimization strategies for hybrid toroidal magnet designs.

用于 10 兆焦耳 HTS SMES 系统的混合环形磁体的电磁优化

超导磁体是超导磁储能（SMES）系统的关键部件，直接影响储能系统的经济效益和稳定性。本研究的重点是 10 兆焦耳 HTS SMES 系统中带有 D 型线圈的混合环形磁体，旨在通过最大限度地降低超导导体的成本来优化其设计。该系统采用了改进的粒子群优化算法（IPSO），该算法整合了混沌映射，并引入了基于 Metropolis 准则的交叉和突变算子。优化过程中考虑了磁体临界电流、超导电缆最小弯曲半径和安全系数等因素。对比分析表明，IPSO 算法在收敛速度和准确性方面优于标准 PSO 算法。最后，本文介绍了 10 MJ HTS SMES 系统混合环形磁体的优化设计方案。本文为混合环形磁体设计提供了优化策略。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
