Abstract:
In a microgrid, faults can lead to voltage instability, which can produce voltage sags, swells, or even a full collapse of the voltage. This may result in electrical equipment damage and interfere with the microgrid's operation. Faults can also produce safety risks including fire, explosion, or electrocution, which can endanger employees and harm equipment. By isolating or shutting down the system when a malfunction is found, the danger of harm or injury is reduced. The purpose of fault isolation and detection in a DC microgrid is to guarantee the microgrid's dependability and safety. The micr

Abstract:
The concept of microgrids has emerged as an effective way to integrate distributed energy resources (DERs) into distribution networks. The presence of DERs in microgrids leads to challenges in the formulation of protection for microgrids. Protection problems arise in a microgrid due to varying fault current levels in different operating scenarios. In order to overcome the practical challenges arising from varying fault current levels leading to short-circuit faults in microgrids, this paper proposes a MagnetoResistive (MR) sensors-based protection scheme, with fault localization through Superi

Abstract:
DC microgrids have gained significant attention in recent years due to their potential to enhance energy efficiency, integrate renewable energy sources, and improve the resilience of power distribution systems. However, the reliable operation of DC microgrids relies on the early detection and location of faults to ensure an uninterrupted power supply. This paper aims to develop fast and reliable fault detection and location mechanisms for DC microgrids, thereby enhancing operational efficiency, minimizing environmental impact, and contributing to resource conservation and sustainability goals.

Abstract:
Microgrids are modern small-scale versions of centralized electricity systems, and due to their complexity and the significant impact of financial loss or damage in the event of a fault, the need for an effective method of fault detection is crucial. This study addressed the critical need for effective fault detection and classification to ensure timely system restoration in the vent of fault.

Abstract DC microgrids can improve energy structure change and enhance the use of new energy sources. However, it is challenging to find series arcs in DC microgrid systems. In order to detect series arc faults in DC microgrids, this study suggests a multi-feature based approach. By calculating the standard deviation of the system arc current, the root mean square(RMS) of the d5 wavelet coefficients and the marginal spectral eigenfrequency amplitude, a triple fault criterion is constituted. Then the threshold comparison weighting method is utilized to achieve fault identification. Finally, the

Abstract:
The dynamic features of microgrid operation, such as on-grid/off-grid operation mode, the intermittency of distributed generators, and its dynamic topology due to its ability to reconfigure itself, cause misfiring of conventional protection schemes. To solve this issue, adaptive protection schemes that use robust communication systems have been proposed for the protection of microgrids. However, the cost of this solution is significantly high. This paper presented an intelligent fault detection (FD) system for microgrids on the basis of local measurements and machine learning (ML) techniques.

Abstract:
With the rapid increase in electrical energy demand, power generation in the form of distributed generation is becoming more important. However, the connections of distributed generators (DGs) to a distribution network or a microgrid can create several protection issues. The protection of these networks using protective devices based only on current is a challenging task due to the change in fault current levels and fault current direction. The isolation of a faulted segment from such networks will be difficult if converter interfaced DGs are connected as these DGs limit their output currents

The evolution of the existing grid system has resulted in bidirectional power flow.
