“…Basically, FCL has a low impedance value under normal conditions that does not affect power flow or quality indices. However, this value drastically increases during faults [151,152]. FCLs are generally classified into two main types: superconductor and solid state FCLs, which are further subdivided into distinct sub-types as detailed in [58,153].…”

With the rapid development of electrical power systems in recent years, microgrids (MGs) have become increasingly prevalent. MGs improve network efficiency and reduce operating costs and emissions because of the integration of distributed renewable energy sources (RESs), energy storage, and source-load management systems. Despite these advances, the decentralized architecture of MGs impacts the functioning patterns of the entire system, including control strategy, energy management philosophy, and protection scheme. In this context, developing a convenient protection strategy for MGs is challenging because of various obstacles, such as the significant variance in short-circuit values under different operating modes, two-way power flow, asynchronous reclosing, protection blinding, sympathetic tripping, and loss of coordination. In light of these challenges, this paper reviews prior research on proposed protection schemes for AC-MGs to thoroughly evaluate network protection's potential issues. The paper also provides a comprehensive overview of the MG structure and the associated protection challenges, solutions, real applications, and future trends.

“…SSFCL current limiting behavior depend on quick acting ON/OFF status change regarding semiconductor switches for inserting current limiting reactor. In order to decrease or limit transient fault currents from growing overly big, a SSFCL could be activated extremely quickly [46,47]. The development of high-power semiconductor technologies, like Emitter Turn-off Thyristors (ETO), emerging SiC devices, new thyristors, and high power IGBTs, enables the implementation of a SSFCL that is commercially practical .…”

The integration regarding various power electronic devices has led to an increase in the complexity of power systems. Limiting the fault currents is crucial for protecting these systems, the augmentation of fault reliability, and the stability. Many Faults Current Limiters (FCLs) were used in power systems because they quickly and effectively fault current limiters. The presented work gives a thorough literature review regarding the use of various FCL types in the power systems. The non-superconducting and superconducting FCL applications have been divided into five categories: (a) application in transmission, distribution and generation networks; (b) applications in the systems of alternating current (AC)/direct current (DC); (c) applications in the integration of renewable sources of energy; (d) applications in the distributed generation (DG); (e) applications for improving stability, reliability, and fault ride through capabilities. With examples of their practical implementation in various nations, impact, modeling, and control approaches of various FCLs in the power systems have been shown. With the alteration of its structures, appropriate control design, and optimal placement recommendations have been given in order to enhance performance regarding FCLs in the power systems. In order to incorporate the continuing research advances in practical systems, industry and researchers working on power system stability concerns can benefit greatly from this study.

“…Integration of multiple distributed power sourcesinto the existing power grid can increase the frequency and magnitude of short-circuit eventsboth at high-voltage and medium/low-voltage levels. This explains the recent interest in fault current limiting technologies [3].If a fault current limiter (FCL) can provide the required protection, a utility can forgo the substation upgrade needed to handle higher fault currents and avoid a substantial capital expense [4,5].…”

Superconducting fault current limiters (SFCL's) are increasingly implemented in the power grid as a protection of substation equipment from fault currents. Resistive SFCL's are compact and light, however they are passively triggered and thus may not be sufficiently sensitive to respond to faults in the distribution grid. Here, we explore theprospect of adding an active management feature to a traditional resistive SFCL.A flexible radio-frequency coil, which is an integral part of the switching structure, acts as a triggering device. We show that the application of a short, 10 ms, burst of acmagnetic field during the fault triggers a uniform quench of the wire and significantly reduces the reaction time of the wire at low currents. The ac field burst generates a high density of normal zones, which merge into a continuous resistive region at a rate much fasterthan that of sparse normal zones created by the transport current alone.
