Reduction of electricity consumption in data centers can be achieved by switching to a direct current power distribution with increased voltage level: The direct parallel coupling of the battery storage to such a distribution grid avoids multiple conversion steps, and the increased voltage level reduces currents. The modular flexible layout allows for easy integration of photovoltaic arrays and storage, and eliminates harmonic injection problems. The D3Bus (Dual DC Distribution Bus), a bipolar DC bus operating at ±1.5 kV is used for the power distribution inside the datacenter.
