In AC microgrid structure, an AC bus is created, and all microsources with variable frequency and variable voltage AC output are connected to AC bus through AC/AC power electronics converter.
Microgrid is an important and necessary component of smart grid development. 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.
AC microgrids: AC microgrids represent the ac power supply in a distribution network. They can be easily connected to an existing grid utility without special requirements such as converters and their control approaches.
In this paper, a comprehensive review is formulated by appropriately recognizing and honoring the relevant key components (aim, MG, and control techniques), related technical issues, challenges, and future trends of AC-microgrid control application.
The review shows that AC microgrids are the most used configuration due to their ability to directly integrate renewable energy sources already connected to current distribution networks with minimum modifications of the electric infrastructure.

6 FAQs about [The basic principle of AC microgrid is]
What control aspects are used in AC microgrids?
Various control aspects used in AC microgrids are summarized, which play a crucial role in the improvement of smart MGs. The control techniques of MG are classified into three layers: primary, secondary, and tertiary and four sub-sections: centralized, decentralized, distributed, and hierarchical.
What is AC microgrid?
This is because of well-established ac power networks with compatible modes of electrical and electronic devices. The distribution system of an ac microgrid can principally be classified as one of three types, single-phase or three-phase with/without neutral-point lines.
Are hierarchical control techniques used in AC microgrid?
A comprehensive analysis of the peer review of the conducted novel research and studies related recent hierarchical control techniques used in AC microgrid. The comprehensive and technical reviews on microgrid control techniques (into three layers: primary, secondary, and tertiary) are applied by considering various architectures.
What is the difference between AC and dc microgrid?
The distribution network of a DC microgrid can be one of three types: monopolar, bipolarn and homopolar. In an AC microgrid, all renewable energy sources and loads are connected to a common AC bus. The main disadvantage of the AC microgrids is the difficulty in the control and operation. A typical structure of AC microgrid is schemed in Figure 5.
What are the components of a microgrid?
They can be used to power individual homes, small communities, or entire neighborhoods, and can be customized to meet specific energy requirements. Microgrids typically consist of four main components: energy generation, energy storage, loads and energy management. The architecture of microgrid is given in Figure 1.
What are microgrids & how do they work?
One way to achieve this is through the use of microgrids, which are small-scale power systems that can operate independently from the traditional grid. They allow communities, businesses, and even households to generate, store, and distribute their own energy, reducing dependence on fossil fuels and the traditional power grid.
