Figure 4 shows the possible blinding zones in the distribution network in the presence of a DG. More possible blinding zones may occur by a DG that is embedded between the feeding substation and the fault point.
They are single facility microgrid, multiple facility microgrid, feeder microgrid and substation microgrid (Bose et al., 2007). A typical configuration of a microgrid is shown in Fig. 1 . It consists of a group of radial

There are many strategies for energy management systems for smart microgrids such as load management, generation management, and energy storage management 4. The control system of a microgrid must continuously analyze and prioritize loads to maintain a balance between power generation and consumption.
While microgrids have many benefits for power systems, they cause many challenges, especially in protection systems. This paper presents a comprehensive review of protection systems with the penetration of microgrids in the distribution network.
It is a small-scale power system with distributed energy resources. To realize the distributed generation potential, adopting a system where the associated loads and generation are considered as a subsystem or a microgrid is essential. In this article, a literature review is made on microgrid technology.
The microgrid control consists of: (a) micro source and load controllers, (b) microgrid system central controller, and (c) distribution management system. The function of microgrid control is of three sections: (a) the upstream network interface, (b) microgrid control, and (c) protection, local control.
The protection system adaptively changes with the topological variations of the power system. References [42, 44] proposed the protection of a microgrid with a communication network using digital relays. These methods use differential protection for low fault currents, such as in an HIF and inverter-based-microgrid.
Smart microgrids (SMGs) are small, localized power grids that can work alone or alongside the main grid. A blend of renewable energy sources, energy storage, and smart control systems optimizes resource utilization and responds to demand and supply changes in real-time 1.
