Abstract
In this paper, the control and protection of a residential direct current (DC) microgrid (MG) is studied. Of particular interest is an ungrounded building grid, which is also galvanically connected to the supplying lowvoltage DC (LVDC) grid. The paper introduces a control strategy for the MG and analyses different faults with PSCAD simulations. A possible protection scheme for the grid is proposed.Publisher
