“…Results show that when TD is set as 0.45 for ground recloser fast curve, the ground recloser always operate first in fast mode during the faults, then followed by the fuses and the ground recloser slow mode. In this way, fuse-ground recloser coordination without PV system is verified with the defined ground recloser fast and slow curve TCC equations as listed in (5)(6).…”

“…In [3][4], the possible loss of fuse-fuse coordination and fuserecloser coordination under the impact of distributed generation (DG) is discussed. In order to mitigate the impact of DG on protection coordination, [5] developed a classification technique for recloser-fuse coordination to find the best DG location with proper recloser settings, [6] proposed a new control strategy to limit the DG output current during faults, and [7] utilized the grounding reactance to reduce the residual fault current from DG.…”

In this paper, an automated approach is presented to verify the impact of different levels of photovoltaic (PV) penetration on the protective device coordination in distribution systems. The approach is implemented on a detailed feeder modeled in OpenDSS. The feeder has been modeled using extensive geographic information system (GIS) data, with loads, PV output and substation voltage modeled using data from advanced metering infrastructure (AMI) and data acquisition systems (DAS), as discussed in [1-2]. Starting from the feeder topology, an adjacency matrix is generated to find the coordinated protective devices during each possible fault in the feeder. The time-current curves (TCC) are created based on the types and ratings of the protective devices installed in the feeder to help classify whether coordination holds or not, under increasing penetration levels and varying locations of the PV system. The fuse-fuse coordination and fuse-recloser coordination during all types of possible faults are verified in this study. The approach implemented can also be utilized in other feeders to help verify the protective device coordination with and without PV penetration.

“…between the recloser location and the fuse, for a fault downstream of the fuse), could act to increase fault current (or cause fault current to persist) for a fault beyond the fuse, resulting in fuse blowing, and potentially resulting in slower recloser operation due to reduced upstream fault current. These coordination problems are discussed further in [22], [23].…”

This paper presents a comprehensive review and detailed investigation of the protection issues that may potentially arise due to the proliferation of technologies such as distributed generator (DG) and energy storage in future power distribution networks. A summary and critical evaluation of several potential protection and control solutions (applicable to the generators or the network), which are proposed as addressing one or more of the identified issues, are also presented. The analysis covers both economic and technological viability and feasibility. Finally, a mapping of the identified issues to the most appropriate proposed solutions is presented, along with discussion, analysis and conclusions. Index Terms-Future distribution network, distributed generators (DGs), protection issues and solution schemes.

“…Some methods of this group use extra PDs such as recloser, breaker, and sectionalizer. This group increases the cost of the protection system. (v)Control of output current of DGs during the fault condition is proposed in Yazdanpanahi et al, Ebrahimi et al, and Fani et al This method reduces the fault current contribution of DGs; however, if the voltage drop across the DG inverter is high, this method leads to the significant reduction of injected power of DG unit (similar to group i). (vi)Adaptive protection is proposed in Shah and Bhalja . In this method, by multiplying the time dial setting (TDS) by the ratio of the current of recloser to the current of the fuse, TDS of recloser fast operation curve is modified.…”

Summary The high penetration level of photovoltaic (PV) units increases their injected fault current that it may result in fuse‐recloser miscoordination in distribution networks. The conventional coordination techniques are based on shifting the fast operation curve of the recloser below the characteristic curve of the fuse for fuse saving in the case of a temporary fault. However, these techniques save fuse if the slopes of fuse and recloser characteristic curves are same. Also, in the case of the high penetration level of PV systems, the conventional schemes are not effective. To address these problems, this paper proposes two fuse saving strategies that not only modify the difference between the slopes of fuse and recloser characteristic curves but also are effective for various penetration levels of PV units in the distribution network. The proposed protection scheme does not require the communication infrastructure and can be implemented in both conventional and digital reclosers installed in the distribution network. The reliable performance of the proposed fuse saving strategies is assessed on the simulation model of the Isfahan distribution network.
