The control design for microgrids is a major issue that needs attention. On the basis of the microgrid SoS structure and framework mentioned previously, a control methodology based on SoS is proposed for microgrids. A hierarchical control structure for the microgrid SoS is illustrated in Fig 5. It can be seen that subsystems (DGs) of microgrid
Hierarchical control structure in microgrids with distributed
The hierarchical control structure of a microgrid can be described as having four levels responsible for processing, sensing and adjusting, monitoring and supervising, and maintenance and optimization. The responsibility of the hierarchical control level is to provide control over the production of power from renewable sources.

A Thorough Overview of Hierarchical Structure of Microgrid Systems
Today, the microgrid system is attracting the attention of many researchers because it brings plenty of benefits to the conventional power system such as enhancing the reliability of the system, reducing the transmission cost, and diversifying energy sources. In fact, a microgrid system is a small-scale of a distribution system including three main elements: (i) distributed
Microgrid
A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and in island mode. [2] [3] A ''stand-alone microgrid'' or ''isolated microgrid'' only operates off-the-grid and cannot be connected to a wider electric power system. [4]Very small microgrids are called nanogrids.
