Fig. 4.2. Master-slave microgrid architecture. The main devices constituting the architecture are described in detail in the following. Utility interface (UI). The UI is an electronic power processor (EPP) equipped with energy storage and connected at the PCC of the microgrid with the utility.
At the beginning of each control period T (lasting a few line cycles) the master controller in the UI polls all the nodes of the microgrid. The active nodes return the values of active and reactive power that are available for microgrid control, while passive nodes may return their active and reactive power consumption.
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.
In MG control systems, the master–slave control strategy is a commonly used approach to manage the power output of DGs . The basic idea of this strategy is to have one DG, usually the most powerful or the most reliable one, acting as the master and the other DGs acting as slaves .
The chapter deals with control of low-voltage microgrids with master-slave architecture, where distributed energy resources interface with the grid by means of conventional current-driven inverters (energy

However, microgrid architectures lack versatility and flexibility in terms of control, limiting their expansion. This paper presents a multi-mode master-slave control approach to increase the flexibility of DC
The article extensively discusses centralized, decentralized, and distributed strategies for each control level, highlighting their differences, advantages, disadvantages, and areas of application. Finally, the
DC microgrid clusters are effective solutions for integrating multiple autonomous subgrids at the same and different voltage levels. In such a system, global power management is an essential concern, but
As distributed generation systems are increasingly integrated on a large scale, research into microgrid control is becoming increasingly vital. The microgrid clusters, which are interconnected via a DC
A hybrid relay was modeled using passive techniques along with a suggestion for the operation of the newly formed Microgrid (MG), presenting a control philosophy of the regulators connected to the grid or
This paper presents a method for supplying stable electricity using renewable energy sources and energy storage systems (ESSs) in a small-scale microgrid (MG) such as an island.
This paper presents a multi-mode master-slave control approach to increase the flexibility of DC-coupled hybrid microgrids.
Recently, predictive control with its fast transient response and flexibility to accommodate different constraints has presented huge potentials in microgrid applications.
