This article aims to provide a comprehensive review of control strategies for AC microgrids (MG) and presents a confidently designed hierarchical control approach divided into different levels. These levels are specifically designed to perform functions based on the MG's mode of operation, such as grid-connected or islanded mode.
The control system should be able to regulate the voltage as well as the frequency, both during islanded operations of the microgrid and grid-tied operation. This paper gives an outline of a microgrid, its general architecture and also gives an overview of the three-level hierarchical control system of a microgrid.
Microgrid can be designed to operate as direct current (DC), alternating current (AC), high frequency alternating current (HFAC) or a combination of these three (i.e DC, AC, HFAC), depending on the need. Figure 2 below shows the general layout of typical DC and AC Microgrid architecture. Figure 2. Layout of Microgrid (a) DC Microgrid
Coordination between DERs. Depending on the type of power supplied, microgrid (MG) topologies are divided into DC, AC, hybrid, and 3-NET [ 4][ 5][ 6]. According to its configuration, MGs are classified into cascade-type and parallel-type MGs.
In fact, a key element of microgrid operation is the microgrid energy management system. It includes the control functions that define the microgrid as a system that can manage itself,

The Microgrid control functions as the brain of the microgrid, and thus requires a complex design consisting of three levels of control: primary, secondary, and tertiary.
This article describes the main types of microgrid control architectures, including centralized, decentralized, distributed, and hierarchical approaches, and compares their
