“…Since there is the tradeoff among several objectives, enhancing one of them might lead to the deterioration of the others. Multiobjective optimization techniques [18,23,107,116] have been reported to solve the above mentioned problem. However, most of the optimal placement techniques do not take into account uncertainties in power systems, especially the unpredictable variations in the status of a DG, wind and PV systems when determining the best location for SFCL [14].…”

Power systems are becoming more and more complex in nature due to the integration of several power electronic devices. Protection of such systems and augmentation of reliability as well as stability highly depend on limiting the fault currents. Several fault current limiters (FCLs) have been applied in power systems as they provide rapid and efficient fault current limitation. This paper presents a comprehensive literature review of the application of different types of FCLs in power systems. Applications of superconducting and non-superconducting FCLs are categorized as: (1) application in generation, transmission and distribution networks; (2) application in alternating current (AC)/direct current (DC) systems; (3) application in renewable energy resources integration; (4) application in distributed generation (DG); and (5) application for reliability, stability and fault ride through capability enhancement. Modeling, impact and control strategies of several FCLs in power systems are presented with practical implementation cases in different countries. Recommendations are provided to improve the performance of the FCLs in power systems with modification of its structures, optimal placement and proper control design. This review paper will be a good foundation for researchers working in power system stability issues and for industry to implement the ongoing research advancement in real systems.

“…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 application of resistive-type superconducting fault current limiters (RSFCLs) in electrical networks is very attractive due to their relative compactness, light weight, and good performance. However, this technology still has drawbacks: asymmetrical quench, uncertain limiting velocity, passive action and incapability of enlarging capacity. Here, we present an active quenching technique which can potentially solve these problems. The quenching process is triggered using highfrequency (HF) AC fields, which are generated by two coupled copper coils attached on both sides of the YBCO sample. Our experiments show that this approach is effective in guaranteeing uniform quench and therefore is expected to be able to significantly extend the service life of the device. Moreover, the quench speed can be considerably increased by the HF field. We find that the performance of acceleration is positively correlated to the transport current, intensity and frequency of the AC field. In addition, a DC magnetic field is added around the sample holder simultaneously with the AC field, to study the field-angular-frequency dependence of the quench time t (B AC f AC B DC θ DC ). Experimental results prove that the DC magnetic field can cooperate with the HF AC field to accelerate quench, which means better performance can be produced with lower costs with the two fields acting together. In all, this technique showed outstanding performance regarding quench acceleration and tape protection. We believe the HF-assisted quenching technology has a promising future in current-limiting devices and hope our findings could be helpful for its potential applications.

Summary Superconducting fault current limiters (SFCLs), as the novel power system devices, have attracted attentions in the last years. However, in order to achieve the maximum benefit from SFCLs, their interaction with power system should be comprehensively evaluated before equipping the power system with them. This paper investigates the effect of fault resistance and fault distance on the steady‐state fault current reduction ratio (FCRR) of hybrid SFCL. Based on the equivalent circuit model, analytical studies are presented to obtain the relation between 2 abovementioned factors and the FCRR of hybrid SFCL. Then, through the detailed simulation studies, the current limiting behavior of hybrid SFCL is evaluated when the value of fault resistance and the position of fault change in wide range. As a result, although the hybrid SFCL is able to reduce the fault current under different circumstances; however, FCRR significantly varies under outside the control changing circumstances. For far faults and faults with high fault resistance, the FCRR of hybrid SFCL is not as good as the other fault conditions. Hence, in the last section of the paper, the remedial actions to enhance the performance of hybrid SFCL during these conditions are proposed.
