How to design a 2G HTS SMEs?

This paper outlines a methodology of designing a 2G HTS SMES, using Yttrium-Barium-Copper-Oxide (YBCO) tapes operating at 22 K. The target storage capacity is set at 1 MJ, with a maximum output power of 100 kW. The magnet consists of a stack of double pancake coils designed for maximum storage capacity, using the minimum tape length.

What is superconducting magnetic energy storage (SMES)?

1. Introduction Superconducting Magnetic Energy Storage (SMES) is a promising high power storage technology, especially in the context of recent advancements in superconductor manufacturing .

What are 2G Superconducting materials?

Second generation (2G) superconducting materials are cuprates of rare earth elements, ReBaCuO (Re = Y, Sm, Gd). Compared to 1G HTS, second generation materials can sustain higher critical currents at similar external magnetic fields, thus improving the performance of SMES units.

Can a redox storage device store more energy faster than an EDLC?

Abstract The use of fast surface redox storage (pseudocapacitive) mechanisms can enable devices that store much more energy than electrical double-layer capacitors (EDLCs) and, unlike batteries, can do so quite rapidly.

What is a 2G HTS SMEs unit?

Conceptual designs of larger 2G HTS SMES units were proposed in several publications, ranging from a 90 kJ YBCO unit for PV transient performance improvement , a 5 MJ YBCO unit for voltage sag compensation and even a 2.4 GJ toroidal YBCO unit for load fluctuation compensation .

Are energy storage devices unipolar?

Furthermore, because energy storage devices are unipolar devices, for practical application, we must consider the non-switching I–V transients, as there will be no voltage of the opposite polarity to switch any ferroelectric polarization that may be present.
