Based on conventional approaches for the integration of resistive-type superconducting\nfault current limiters (SFCLs) on electric distribution networks, SFCL models\nlargely rely on the insertion of a step or exponential resistance that is determined by a\npredefined quenching time. In this paper, we expand the scope of the aforementioned\nmodels by considering the actual behaviour of an SFCL in terms of the temperature\ndynamic power-law dependence between the electrical field and the current density,\ncharacteristic of high temperature superconductors. Our results are compared to the\nstep-resistance models for the sake of discussion and clarity of the conclusions. Both\nSFCL models were integrated into a power system model built based on the UK power\nstandard, to study the impact of these protection strategies on the performance of\nthe overall electricity network. As a representative renewable energy source, a 90 MVA\nwind farm was considered for the simulations. Three fault conditions were simulated,\nand the figures for the fault current reduction predicted by both fault current limiting\nmodels have been compared in terms of multiple current measuring points and\nallocation strategies. Consequently, we have shown that the incorporation of the Eââ?¬â??J\ncharacteristics and thermal properties of the superconductor at the simulation level\nof electric power systems, is crucial for estimations of reliability and determining the\noptimal locations of resistive type SFCLs in distributed power networks. Our results\nmay help decision making by distribution network operators regarding investment and\npromotion of SFCL technologies, as it is possible to determine the maximum number\nof SFCLs necessary to protect against different fault conditions at multiple locations.
