Survey on DC microgrid architecture, power quality issues and control strategies

In the evolving power system, DC micro-grid is an attractive alternate structure given its smooth interface with renewable power sources, electric loads, and storage technology. This paper presents a survey of the important research works already reported focusing on various power quality issues and control strategies related to dc microgrid. Different control concepts such as fuzzy control, droop control, hierarchical control and multi agent based control have been briefly discussed in this paper. Various configurations of DC microgrid have been comprehensively covered and reviewed.
