This paper reviews the status of hierarchical control strategies applied to microgrids and discusses the future trends. This hierarchical control structure consists of primary, secondary, and tertiary levels, and is a versatile tool in managing stationary and dynamic performance of microgrids while incorporating economical aspects.
The control system should be able to regulate the voltage as well as the frequency, both during islanded operations of the microgrid and grid-tied operation. This paper gives an outline of a microgrid, its general architecture and also gives an overview of the three-level hierarchical control system of a microgrid.
The architecture of an MG depends on a number of factors such as availability of renewable resources, geographical location of site, load demand etc. For effective and efficient operation, unlike the main grid, the Microgrid (MG) needs to employ special and proper control strategies.
Figure 1 shows a microgrid schematic diagram. The microgrid encompasses a portion of an electric power distribution system that is located downstream of the distribution substation, and it includes a variety of DER units and different types of end users of electricity and/or heat.

Advanced control strategies are vital components for realization of microgrids. This paper reviews the status of hierarchical control strategies applied to microgrids and discusses the future trends. This
The control structures require a complex design with three different levels of hierarchy, these being the primary, secondary, and tertiary levels, each with unique capabilities and vulnerabilities. The
The most basic structure of the microgrid is divided into three layers,as depicted in Fig. 1.5--local control (LC) layer in the bottom,followed by centralized control (CC) layer,and in the uppermost is the distribution network
