The future electric grid faces challenges by a rising share of renewable generation. This development increases the number of smaller decentralized power plants and therefore the volatility of energy generation. A technical approach to overcome these challenges is to cluster distributed energy generation and local power demand in microgrids. These can be used to balance power generation and demand locally and in short time frames. The industry relies on an high quality and reliable power supply, which can be ensured in a microgrid architecture, even if the main AC power grid does not meet the requirements. In specific industrial applications prototypes of direct current (DC) microgrids are built. Such a multi terminal architecture is in need for a grid control that adjusts the respective power flow of each device. This study aims on determining the implications for the DC microgrid design process with respect to stability of the control system.
