Optimal location and minimum number of superconducting fault current limiters for the protection of power grids

Abstract: This paper presents a novel method to determine the optimal strategy for the allocation of multiple resistive superconducting fault current limiters (SFCLs) aiming to improve the overall protection of standard power grids. The presented approach allows for the straightforward determination of the optimal resistance of the SFCL, accounting for short circuit events occurring at different locations, by modelling the electro-thermal properties of the SFCL via a temperature dependent E-J power law.

“…YBCO-coated conductors are one of the most promising superconducting materials that can be used in the power system. The most successful HTS devices, including superconducting fault current limiters, power transmission cables and transformers, have shown their superiorities and potentials compared with their conventional alternatives [5,6]. Moreover, the cost-performance ratio is getting better thanks to the progress in material researches, which facilitates further development of superconducting applications.…”

“…On the other hand, in order to handle the increased fault current, protection equipment such as fuses and breakers should be replaced with higher rating equipment, which is a time consuming and expensive approach. Utilizing fault current limiters (FCLs) is one of the most attractive techniques to overcome these problems . During normal operation of power system, these facilities have negligible effect on the power system.…”

“…Utilizing fault current limiters (FCLs) is one of the most attractive techniques to overcome these problems. [8][9][10][11][12][13][14][15] During normal operation of power system, these facilities have negligible effect on the power system. However, they limit fault current through an impedance when a fault occurs.…”

“…High fault current levels have severe impacts on power systems. They increase the likelihood of overcurrent damage which may give rise to destruction of electrical facilities or even system blackout [1][2][3][4]. The superconducting fault current limiter (SFCL) is a device that can help mitigate the increasing level of fault current X.
