Storage Battery Capacity Reduction Effect on 400V-class DC Power Supplied Office with Consideration for Renewable Energy Ratio

In this paper, we derive the relationship between the storage battery capacity reduction effect and the renewable energy ratio (RER) in a building by numerically analyzing each demand curve according to the building use when applying a 400 V-class DC power distribution system. Furthermore, from the numerical analysis results, we report the evaluation results of the condition where the DC power distribution system is more advantageous than the AC power distribution system.
