A Thorough Overview of Hierarchical Structure of Microgrid Systems

Abstract: 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

A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. It is able to operate in grid-connected and in island mode. A ''stand-alone microgrid'' or ''isolated microgrid'' only operates off-the-grid and cannot be connected to a wider electric power system. Very small microgrids are called nanogrids. A grid-connected microgrid normally operates connected to and synchronous with the traditional
