Complex microgrid hierarchical structure diagram

Are hierarchical control strategies applied to microgrids?

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.

What is the nature of microgrid?

The nature of microgrid is random and intermittent compared to regular grid. Different microgrid structures with their comparative analyses are illustrated here. Different control schemes, basic control schemes like the centralized, decentralized, and distributed control, and multilevel control schemes like the hierarchal control are discussed.

What are the components of microgrid control?

The microgrid control consists of: (a) micro source and load controllers, (b) microgrid system central controller, and (c) distribution management system. The function of microgrid control is of three sections: (a) the upstream network interface, (b) microgrid control, and (c) protection, local control.

What is the tertiary control structure in a community microgrid?

Aiming at a community microgrid with multiple AC and DC sub-microgrids, the hierarchical control structure is proposed to achieve the economic and coordinative control.especially, the tertiary control is implement to ensure the optimal coordination of an islanded community microgrid .

Is a microgrid a complex system?

It is worth noting that the microgrid is a complex system comprising of variety of subsystems which are non-linear and possess strong cross-coupling between them. Therefore analysing the microgrid from an intelligent SoS perspective is the need of the hour.

Which architecture and control methodology is best for microgrids?

According to Xiao et al. , there is not still a consensus as to which architecture and control methodology is the best for microgrids. It is worth noting that the microgrid is a complex system comprising of variety of subsystems which are non-linear and possess strong cross-coupling between them.
