Abstract: With the continuous development of the global economic level, global energy consumption is also on the rise, and the global power industry is faced with a number of formidable challenges including load growth, low energy efficiency, high power quality, and environmental protection. Despite the fact that distributed energy cannot be directly connected to the power grid, the concept of the microgrid (MG) is proposed to make better use of distributed energy and reduce its effect on the power grid. The low cost and high controllability of DC MGs have piqued the interest of academicians both at home and abroad. If DC MGs are to be implemented in real-world engineering, a stability control strategy is required; therefore, research on voltage stability and coordinated control of DC MGs is extremely important and promising. This paper summarizes the current research on the voltage control strategy of the DC MG from the perspective of the voltage control strategy of the DC MG. Lastly, it is proposed that the future development of DC MGs will be more focused on intelligence and control precision and that the consistency algorithm combined with the benefits of centralized control and distributed control can effectively aid the future development of DC MGs, taking into account the grid’s dependability and control precision.
