A Systematic Literature Review on AC Microgrids
The objective of this work is to analyze and compare AC microgrid (ACMG) solutions to introduce the topic to new researchers. The methodology used to achieve this goal is a systematic literature review
Typically, AC microgrids consist of distributed generation sources such as renewables, and conventional power generation sources such as engine-based generators. These distributed generators are connected through an AC bus system with an energy storage medium like battery energy storage system (BESS).
A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island mode”. Microgrids can enable grid modernization, allow the integration of renewable energies, reduce peak loads and losses by locating generation near demand, ensure power availability for critical loads, and may support the main grid .
The microgrid configuration can be dc, ac, or hybrid. The ac microgrid is more focused nowadays due to its ability to operate in conjunction with main grid, simple structure and cost effectiveness. The typical structure of a microgrid is shown in Fig. 1. The inverter act as an interface between distributed energy resources and utility grid.
If the bus works in alternating current (AC), the microgrid can be called an AC microgrid, if the bus is direct current (DC), the microgrid is known as DC microgrid, and if it has both AC and DC buses, it is known as a hybrid microgrid.

Microgrids are classified into two groups: AC Microgrids and DC Microgrids (“Alternating Current” and “Direct Current”) microgrids based on their operational setup.

What is a Micro Grid? Definition and Applications Modern societies face increasing challenges, with rapid urban expansion and increasingly frequent natural disasters exacerbating the strain on
A large university campus in Denmark deployed an AC microgrid to achieve energy independence, reduce carbon emissions, and maintain power reliability across campus buildings.
The cost-effectiveness of each microgrid type depends largely on the specific application and system design. Conclusion: Choosing the Right Microgrid Selecting between AC and DC
An ac microgrid is defined as a power system that includes loads, distributed generation, and energy storage, managed as a single unit to exchange power with the main grid through a single coupling
