Abstract
In this paper, the control algorithm of DC microgrid by using voltage compensation term is proposed for energy management and minimization of voltage variation. The droop control has a disadvantage in that it necessarily generates voltage variation and energy management is difficult. To solve these problems, the voltage compensation term through communication between different units is used as an index for energy status of DC microgrid. By setting the operation band and designing the droop gain and nominal voltage, energy management and minimization of voltage variation can be achieved.
