Multilevel Robust Design Optimization of a Superconducting Magnetic Energy Storage Based on a Benchmark Study

Abstract

Superconducting magnetic energy storage (SMES) systems with different superconducting materials are attracting great attentions and funding from the governments around the world because they are promising large-scale energy storage devices for future smart grid. Due to the high cost of SMES, its manufacturing quality and operation reliability have to be investigated in the design optimization stage. This paper presents a robust design optimization framework to solve this issue based on a benchmark problem, TEAM problem 22. The proposed robust design optimization is based on a technique called design for Six-Sigma. Meanwhile, a modified multilevel optimization strategy is employed to reduce the computation cost of finite element analysis due to high-dimensional design space and Monte Carlo analysis. As shown, the reliability and manufacturing quality of the investigated SMES after robust optimization have been increased greatly.  Index Terms-Manufacturing quality, multilevel optimization, robust optimization, superconducting magnetic energy storage.

Future Power Distribution Grids: Integration of Renewable Energy, Energy Storage, Electric Vehicles, Superconductor, and Magnetic Bus

“…SMES has the ability to go from full charge to full discharge very quickly, which would make it extremely useful for integration with renewables to mitigate its adverse impacts. A suitable core needs to be designed to allow SMES to have high stored energy [21]. A suitable application of this new technology is to mitigate the renewable energy impacts.…”

“…A suitable application of this new technology is to mitigate the renewable energy impacts. In the past, it was not possible because of the high-cost of superconducting coil for SMES [21]; however the cost is now reducing due to new development of HTS technology.…”
