The power distribution network will be changed towards the future Smart Grid due to increased number of installed renewable power generation units to fulfill the tightened environmental regulation. At the same time, the customers are
highly dependent on uninterruptable, high quality power supply. The challenging Smart Grid control is intensively studied. It can be concluded that the control might be simpler and the grid operation more reliable if the AC grid would be replaced by DC grid. The ±750 V low voltage DC distribution network supplying
four households has been successfully tested in Finland since 2012. The medium voltage is rectified and converted back to AC at the customer connection point.
