“…Meanwhile, evaluation agents in the upper layer scrutinize and assess the modifications for further improvements or upgrades [144,145]. In [146][147][148][149], the deployment of multiagentbased protection methods in MGs is examined for fault detection, relay configuration updates, and maintaining adequate coordination, though high impedance faults and communication failures offer significant restrictions in the use of such strategies.…”

With the rapid development of electrical power systems in recent years, microgrids (MGs) have become increasingly prevalent. MGs improve network efficiency and reduce operating costs and emissions because of the integration of distributed renewable energy sources (RESs), energy storage, and source-load management systems. Despite these advances, the decentralized architecture of MGs impacts the functioning patterns of the entire system, including control strategy, energy management philosophy, and protection scheme. In this context, developing a convenient protection strategy for MGs is challenging because of various obstacles, such as the significant variance in short-circuit values under different operating modes, two-way power flow, asynchronous reclosing, protection blinding, sympathetic tripping, and loss of coordination. In light of these challenges, this paper reviews prior research on proposed protection schemes for AC-MGs to thoroughly evaluate network protection's potential issues. The paper also provides a comprehensive overview of the MG structure and the associated protection challenges, solutions, real applications, and future trends.

“…The published research on microgrid protection has not led to a commercially available microgrid relay, according to [19]. Nevertheless, several microgrid protection schemes have been proposed, such as differential, central, undervoltage, distance, adaptive overcurrent, and time-domain protection schemes, to name a few [20]- [24]. Depending on the microgrid type, topology, and type of the DER, these protection schemes might function competently.…”

This paper proposes a time-domain-based protection scheme for radial and loop microgrid systems with inverter-based resources (IBRs), such as solar photovoltaic (PV) and type-4 wind turbines. The protection scheme is designed to function during both grid-interconnected and grid-isolated modes. The proposed scheme provides an ultra-high-speed sub-cycle directional element aided with low bandwidth communication between relays. Like directional comparison schemes, relays identify whether faults are inzone or out-zone. The directional element is based on time-domain superimposed quantities and Park's transformation algorithms. More specifically, the element calculates the superimposed positive-sequence direct component of transient energy during faults. Superimposed voltage and current quantities are calculated using delta filters and decoupled double synchronous reference frame (DDSRF) filters. The proposed filtering method improves the reliability of the superimposed directional element when IBRs are present. The protection scheme is evaluated on a modified IEEE 34-bus distribution system simulated using an electromagnetic transients program.
