DC microgrid topology. DC microgrid has just one voltage conversion level between every dispersed sources and DC bus compared to AC microgrid, as a result, the whole system’s construction cost has been decreased and it also simplifies the control’s implementation , .
The energy management role is to provide information about system generation and distribution of energy supply at minimal operational costs. In energy management methodologies in microgrids, there are many methods based on linear programming, non-linear programming, and artificial intelligence methods.
The term “microgrid” refers to the concept of a small number of DERs connected to a single power subsystem. DERs include both renewable and /or conventional resources . The electric grid is no longer a one-way system from the 20th-century . A constellation of distributed energy technologies is paving the way for MGs , , .
DC microgrid architecture with their application, advantage and disadvantage are discussed. The DC microgrid topology is classified into six categories: Radial bus topology, Multi bus topology, Multi terminal bus topology, Ladder bus topology, Ring bus topology and Zonal type bus topology.
The energy management of a DC-based microgrid has only been studied in a limited number of cases using classical techniques. The majority of research is geared toward optimizing the size of standalone hybrid renewable energy systems (HES).
