A lot of electrical devices have to transform alternating current (AC) into direct current (DC)
because they work on direct current. Besides that a lot of decentralized energy sources and
electrochemical storage produce or work on direct current. To check whether there is a
possibility for realization and to show up advantages, we are going to do research on low
voltage dc-power grids. We will investigate the feasibility and the necessary components as
well as algorithms to operate and control such a DC-grid. With extended algorithms it should
be possible to realize a “smart DC-grid”. The economical evaluation will indicate the
possibility for realization or the additional demand for research in this area.
