Digital grid in low-voltage distribution system

If distributed generators are introduced on a large scale to the power system, various impacts on the power system are expected. For example, difference between power supply and power demand is occurred in low-voltage distribution system. Digital Grid can solve these problems by performing a power interchange between the power systems. In this paper, we conducted verification and evaluation for Digital Grid in low-voltage distribution system by simulations. We verified whether it is possible to balance power demand and power supply in a house by performing a power interchange between each house and the power system and performing a power interchange between each house. Based on the verification results, we could confirm that it is possible to perform those. We consider that these can contribute to expand introduction of distributed generators to low-voltage distribution system and to improve power supply reliability of low-voltage distribution system.
