DC microgrids (DCMGs) have significant advantages, but their protection can be a challenge for DCMGs expansion expressly in distributed generation sources’ (DGS) tendance. This paper proposes a quick, and precise strategy to perceive and trip any fault in DCMGs in the free tendance of DGS. A bi‐level multi‐agent system (MAS) is proposed to protect the DCMG and DGs. The MAS first level perceives the fault in DCMG via a discrete wavelet transform (DWT). The multiply of two harvest levels’ summation of DWT is exerted to detect and distinguish DC lines faults. The MAS second level detects the fault in DGS and their switchers to the point of common connection (PCC) via a differential pole (DP) controller. A four bus DCMG containing solar PV and wind sources is implemented, and the results demonstrate that the proposed plan can recognize and trip the fault by 100% of reliability.

“…The relay setting was divided into three parts by using a self-organizing map classification approach. In (Bamshad and Ghaffarzadeh, 2023), the miscoordination problem produced due to DERs was solved by using a quadratic multi-agent. Different agents were developed to handle specific protection and coordination issues, and a relay trip signal was generated to operate the breaker based on the output of all agents.…”

“…Additionally, certain schemes (Tsimtsios et al, 2019;Yin et al, 2021) are only applicable to inverter-interfaced microgrids. Adaptive overcurrent protection schemes (Jain et al, 2018;Ghadiri and Mazlumi, 2020;Elsadd et al, 2021;Gadde et al, 2022;Bamshad and Ghaffarzadeh, 2023) necessitate prior knowledge of all operating scenarios and involve complex and sophisticated calculations to determine the relay settings. Fault current limiter (FCL)-based schemes (Dehghanpour et al, 2016;Alam, 2018;Alam et al, 2021) are expensive and impractical.…”

The integration of Distributed Energy Resources (DERs) into distribution grids has become increasingly feasible and sustainable due to the development of microgrids. However, the development of an effective protection strategy remains a challenge in the implementation of microgrids. To address this challenge, this paper presents a simple and novel microgrid protection method based on superimposed components, Wigner distribution function (WDF) and alienation index-based. The proposed method develops a new fault detection index (FDI) by applying the alienation coefficient and WDF on a superimposed current signal to detect faulty events in the microgrid. The scheme is inherently phase segregated because the FDI is obtained for each phase individually. In addition, the proposed strategy introduces a new fault zone identification method based on the superimposed positive sequence reactive power (SPSQ). After obtaining the complete fault information, a relevant trip signal is generated to isolate the faulty section from the rest of the grid. The proposed methodology is evaluated through simulations using MATLAB/SIMULINK software. Various fault types, with varying parameters are simulated to validate the proposed approach. The results indicate that the proposed methodology is capable of recognizing, classifying, and locating all fault types in both grid-connected and islanded modes of operation.

Furthermore, in both studies [44][45][46][47], the proper restoration technique for protecting coordination prior the fuse melting and burning out, which is to classify and relies upon peer-to-peer communications that only reduces the numeral of relay aspects layer only.…”

This study aims to evaluate the impact of the distributed generator (DG) connection to the grid. The simulated results present the parameters of the system required to install DG on the end of the main distribution feeder. Various parameters, such as voltage, current, and protective relay coordination are modelled after the actual provincial electricity authority (PEA) distribution system. Various case studies compared the coordination without and with DG connections to the grid by finding the difference of protective devices. The results indicate that the malfunction can be fixed in order of priority protective devices, which operate according to the parameter setting. Additionally, the coordinate functions between the recloser and fuse devices in both phase and ground configurations in the operating zone prevented the drop-out fuse melting or burning out. Based on the result, this problem is fixed by providing a directional recloser device and increasing the fuse-link rated with 40k installation for replacing the conventional sizing, which can improve the performance in case of fault occurrence to investigate the reliability and stability of the distribution system.
