Grid-connected AC microgrid

Is a grid-connected hybrid alternating/direct current (ac/dc) microgrid based on a wind turbine?

In this paper, we study the modeling, the control, and the power management strategy of a grid-connected hybrid alternating/direct current (AC/DC) microgrid based on a wind turbine generation system using a doubly fed induction generator, a photovoltaic generation system, and storage elements including hydrogen storage system and batteries.

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.

Why do we need AC microgrids?

The decreasing accessibility of fossil fuels has necessitated a greater dependence on renewable energy sources, such as solar systems, wind power, and hydroelectric power, by the international community. As a result, there is an increasing demand for AC microgrids to offer an effective approach for distributing power.

What is AC/DC hybrid microgrid (HMG)?

In Reference 32, the structure of an AC main grid or ACMG is directly connected to the point of common coupling (PCC) in HMG and, DCMG is connected to the AC bus through a bidirectional AC/DC converter. 14 There are two important operating modes of AC/DC hybrid microgrid (HMG): grid-connected and islanded mode.
