“…Research in [32] asserts that safeguarding microgrids at the POI (Point of Interconnection) is challenging. Because the microgrid provides very little fault current, it is challenging to detect single-line-to-ground (SLG) failures.…”

Microgrid fault identification models are developed via integration of extensive data collection, pre-processing of collected data, current & voltage segmentation, feature representation, identification of variant feature sets, their classification & post-processing operations. Existing models that perform microgrid fault identification are either highly complex, or cannot be applied for heterogeneous fault types. Moreover, these models also showcase large variance in terms of their qualitative & quantitative performance levels. Due to these issues, it is difficult for researchers to identify optimum models for their performance-specific deployment use cases. To overcome these issues, a detailed review of different microgrid fault detection & mitigation models in needed, which can evaluate their performance in terms of qualitative & quantitative parameters. Thus, this text initially discusses characteristics of some of the recently proposed microgrid fault detection models in terms of their functional nuances, application specific advantages, deployment specific limitations, and context-specific future research scopes. After referring this discussion, it was observed that linear models that incorporate pattern recognition are highly useful for fault pre-emption and mitigation purposes. This text also compares these models in terms of their accuracy of detection, delay needed for fault identification, computational complexity, deployment cost, and scalability metrics.

“…The result of the proposed scheme is compared with distance relay, as a well-known fault-locating device in AC power systems [ 23 ]. As shown in [ 24 , 25 , 26 ], in addition to transmission lines, distance relays can be implemented in distribution systems. To accurately compare these two different schemes, a distance relay is implemented in the mainstream of the test case, at the same place as the installed overcurrent relay in Figure 4 .…”

Many distribution systems have several branches with only one protection system at the upstream system. This characteristic degrades the performance of traditional fault location schemes. In this paper, a localized fault location method based on the transient behavior of fault currents by using local data is proposed. The proposed scheme uses only local current and the voltage of the upstream overcurrent relay as input data of the fault location scheme. The formulation considers fault resistance, loads, and different fault locations. Furthermore, due to the usage of transient fault current data, the proposed method locates the fault within several milliseconds with a suitable range of error. To validate the effectiveness of this method, field measurement data, obtained from a real distribution system in East Jutland, Denmark operated by Dinel A/S, are used, and extensive real-time simulations are performed. The results prove that the proposed method locates different types of faults within an appropriate time and error, which can improve the maintenance and reliability of distribution systems.

“…In addition, several strategies use different methodologies to define their approach: some are based on voltage drop (Ma et al, 2015) or voltage amplitude comparisons (Liang et al, 2020). Other schemes deal with more specific problems such as determining the fault direction (Chen et al, 2018) or the protection challenges associated with the point of interconnection, as in El-Arroudi &Joós, 2018 andYin et al, 2021. The latter also considers the change produced by the connection of the power transformer at that point, which affects the impedance calculation seen by relay 21.…”

Objective: This paper presents a qualitative comparison of different recently proposed network protection schemes that are based on the distance function. From this comparison, possible opportunities are identified to develop strategies oriented towards protecting active distribution systems. Methodology: This research is carried out in two parts: the first is to identify the fundamental theoretical aspects of distance protection, its main problems, and a description of the most important aspects of the relevant strategies proposed in recent years. The second part consists of selecting aspects and elaborating a qualitative comparison of the different protection schemes analyzed. This comparison makes it possible to establish the advantages and disadvantages of each of the relevant proposals used in conventional electrical networks or active distribution networks. Results: As a result of this research, the most important aspects to consider in the protection design are identified, which therefore strongly affect its performance. These are summarized in a comparative table, which supports future research related to distance protection in active distribution networks. Conclusions: From this research, it can be stated that the solutions analyzed, despite being relevant within the scope of distance protection applied to active distribution networks, have problems to solve. None of these strategies protects the network for all types of failures in a selective, sensitive, reliable, and cost-effective way while guaranteeing minimum supply interruption to consumers. Funding: This paper is a result from projects 6-20-6 funded by Universidad Tecnológica de Pereira and contract 774-2020 (Integra2023) funded by Minciencias, Colombia.
