The high temperature superconducting magnetic energy storage (HTS-SMES) system has an efficient system and is able to storing energy in high density. Therefore, this is an attractive method of energy restore in power system for protection and stability control. In the other hand, one of the most important challenges in HTS-SMES is optimal coil design that have direct relationship with energy stored in unit length of the coil conductor, length of the wire is used, and finally the cost of the winding. In order to resolve design problems, a recent three-objective optimization of the mechanical stress of a coil, uniformity of the magnetic field inside the magnet and coil volume is presented in this paper. Three constraints include energy requirements, the stray field in an around coil, the quench condition and maximum mechanical stress of the HTS-SMES coil are considered. To optimize this three objective optimization design problem, multi objective evolutionary algorithm based on decomposition (MOEA/D) has been used. We optimized step-shaped solenoid coil with maximum mechanical stress and current density constraints. 400 MA/m2 and stresses of about 400 MPa. HTS-SMES solenoid optimal design based on YBCO is considered and the YBCO-coated conductor is employed for the HTS-SMES coil. In this paper, FYSC-SC05 YBCO and FYSC-SC10 tape produced by FUJIKURA superconductor technology company are chosen In this method, in addition to mechanical stress determination, dimension of the HTS-SMES step-shaped cross sectional solenoid is determined. Results show that mechanical stress in FYSC-SC05 and FYSC-SC10 13.5%, 22.3% reduced related to maximum limitation of mechanical stress, respectively.
