Microgrid communication system and its application in hierarchical control

Abstract To meet the fast growing energy demand, the microgrid is proposed and its communication system is designed to ensure the information transmission of distributed generations. In this chapter, the structure and categories of microgrid communication system are studied, and the application of microgrid communication system integrating consensus algorithm is introduced. On this basis, a distributed hierarchical control method is established based on the communication system to balance the battery state of charge (SoC) in decentralized battery energy storage system (DBESS). In order to verify the corrective of this control method, cases of DBESS with three batteries are developed under different operation conditions. Similarly, the analysis of results is discussed in this chapter.
