“…This scheme does not require communication links and DG unit information; however, it requires solving an optimization problem and installing an extra device. In [13], flexible protection coordination is provided by the installation of the FCL in the distribution system. This scheme increases reliability without the need for heavy calculations, communication links, and connection status of DG units.…”

“…By making the quasi-voltage current term, the effect of the far/near point to the fault location on M is determined. Then, the recloser pickup current I pickup,pro is adjusted proportionally to the recloser current by a linear characteristic curve using (13). In the next stage, the recloser time coefficient TMS is adjusted using (14) or (15) depending on the protection system requirements.…”

“…The presence of DG units changes the current profile of the distribution system. Since the protection system of distribution networks is based on the current measurement, this change poses some challenges for the protection system operation [13,34,[41][42][43][44][45][46]. However, the significant advantages of DG units have led distribution system engineers to modify the protection system for tackling these challenges [4,17,47].…”

Increasing the penetration level of distributed generation (DG) units requires overcoming the technical challenges associated with their integration into the distribution systems, especially protection problems. Change in the current profile of the distribution system due to the presence of DG units disrupts the operation of the conventional fuse saving coordination (FSC) scheme. The first objective of this paper is to provide an overview of the state‐of‐the‐art of FSC schemes in distribution systems with distributed generators that has not been systematically presented yet. In addition to comparing the features of reliability, cost, speed, implementation, calculation burden, and requirements, the impact of presence of distributed generations on the performance of the conventional FSC scheme is investigated in details. The second objective of this paper is to propose an FSC restoration scheme for minimizing the challenges of previous works. Using a quasi‐voltage current term, the proposed scheme modifies the adjustable time coefficient of the recloser in two ways of pro and plus. The former scheme provides an approximate FSC with a simple setting while the latter scheme provides complete coordination at the expense of a more complex setting. No need for voltage measurement makes its implementation practical in available distribution systems. The effective performance of the proposed FSC scheme is verified through extensive simulation studies in the ETAP environment.

“…Since the fault type is identified before reclosing, it is named as adaptive reclosing. In ac systems, adaptive reclosing methods mostly utilize the recovery voltage generated by the coupling effect between the fault and healthy phases to distinguish temporary and permanent faults [15,16]. However, there is no coupling between different poles of the dc line, so the above method is no longer applicable.…”

The hybrid dc circuit breaker (HCB) has the advantages of fast action speed and low operating loss, which is an ideal method for fault isolation of multi-terminal dc grids. For multi-terminal dc grids that transmit power through overhead lines, HCBs are required to have reclosing capability due to the high fault probability and the fact that most of the faults are temporary faults. To avoid the secondary fault strike and equipment damage that may be caused by the reclosing of the HCB when the permanent fault occurs, an adaptive reclosing scheme based on traveling wave injection is proposed in this paper. The scheme injects traveling wave signal into the fault dc line through the additionally configured auxiliary discharge branch in the HCB, and then uses the reflection characteristic of the traveling wave signal on the dc line to identify temporary and permanent faults, to be able to realize fast reclosing when the temporary fault occurs and reliably avoid reclosing after the permanent fault occurs. The test results in the simulation model of the four-terminal dc grid show that the proposed adaptive reclosing scheme can quickly and reliably identify temporary and permanent faults, greatly shorten the power outage time of temporary faults. In addition, it has the advantages of easiness to implement, high reliability, robustness to high-resistance fault and no dead zone, etc.
