New technique for power sharing in DC microgrids
MetadataShow full item record
A microgrid (MG) is a cluster of loads and distributed generation units (DG) that are located in a close distance from each other. In a dc MG, the DGs generate a dc voltage and the loads consume power while supplied by a dc voltage. The power sharing amongst DGs is one of the main control issues in dc MGs. Power sharing is conducted in either form of load current or power sharing; however, many of existing techniques assume a single load in the MG. This paper proposes a different technique which can be applied for both current load and power sharing techniques, and in single or multi-loads. The performance of the proposed methods is evaluated through simulation analyses, realized in MATLAB/Simulink®, during various loading demands, DGs capacities and in single or multi loads.
