“…Applying FCL in the network as a solution for the negative impact of penetration of DGs has many challenges as it is considered the extra cost and short life in comparison to the traditional circuit breakers, and maintenance cost. To overcome these issues and any negative impact from using FCL in the network in the operation of the protection devices, a proper allocation for the FCL should be executed for efficient and practical usage of FCL [56].…”

the desire of the consumers for a cheap and reliable energy source in comparison to the large generators, DGs penetration increased as they have smaller capacities, cheap operating costs, low environmental pollution, high efficiency, voltage profile improvement, and enhance the capacity of the electrical grid [1,2].Despite the huge benefits gained from the penetration of DGs, the large penetration leads to conflicts in the protection system of distribution systems as the design of distribution networks is a radial network, and penetration of DGs changes the nature of the network [2].The protection system in the distribution network contains different types of protection devices such as overcurrent relays, and a combination of fuses, and reclosers. These devices are configured in the distribution network as the overcurrent relay is suited at the distribution system substations, reclosers are installed on main feeders, and fuses

“…A number of studies, such as superconducting cables, transformers and energy storage systems, have reported their advantages in reducing the transmission losses and enlarging the current-carrying capacities [3][4][5]. However, with the continuously elevated voltage level and expanded transmission capacity, the possible fault current gradually exceeds the breaking threshold of existing circuit breakers, and more attention needs to be paid to the potential threat it poses to the power grid [6,7].…”

The superconducting fault current limiter (SFCL) improves the power grid safety by restricting the drastically increased current when the circuit fault occurs. However, the SFCL suffers from a long recovery time and can hardly recover to the superconducting state before the breaker attempts to reclose, which hinders its practical application. This paper presents the implementation of the rapid-recovery SFCL with efficient heat dissipation even if encountering a large fault current. This is enabled by thermal performance regulation of the working coolant through adding tetrafluoromethane (CF4) into the liquid nitrogen (LN2). The proposed mixed coolant features a high critical heat flux that suppresses the onset of film boiling. Controlled experiments were performed with the fabricated current-limiting coil immersed in the N2/CF4 mixed coolants containing 0, 20 and 40 mol% of CF4. Measured results regarding both quenching and recovery processes are reported, demonstrating an 85.4% reduction in recovery time for the 40 mol% composition compared to the conventionally used pure LN2. Analyses of the electrical parameters of the coil verify its effective quenching performance in the proposed immersion cooling system with an overall current limiting rate of over 55%. These findings lay a foundation for designing the rapid-recovery-type SFCL and facilitating its application in power systems.
