ICT设施和数据中心的电力消耗不断增加，因此需要提高这些设施的能源效率。对于世界各国开发和部署商业服务而言，采用 380VDC 作为电源电压的直流配电系统是解决这一问题的一种有前景的方法。美国德克萨斯大学奥斯汀分校和日本NTT FACILITIEIS组成的国际团队在美国德克萨斯州展示了与太阳能发电系统互连的380VDC配电系统。此次演示的目的是为了展示380VDC供电系统比交流供电系统更节省能源，并展示通过集成太阳能发电系统可以减少多少二氧化碳排放。与具有相同可靠性水平的交流电源系统相比，本次演示的能耗降低了约 17%。此外，还使用数据中心性能单位能量（DPPE）作为数据中心效率的性能指标进行了评估。结果表明，与交流供电系统相比，380VDC 供电系统的 DPPE 子指标之一的电力使用效率 (PUE) 有所改善。
Power consumption of ICT facilities and data centers has grown, and this has led to a need to improve energy efficiency of these facilities. DC power distribution systems employing 380VDC as the supply voltage is one promising approach to address this problem for countries around the world developing and deploying commercial services. The international team by the university of Texas, Austin, USA and NTT FACILITIEIS, Japan demonstrated a 380VDC power distribution system interconnected with a solar power generation system in Texas, USA. The purpose of this demonstration was to show that a 380VDC power supply system saves more energy than an AC power supply system, and to show how much carbon dioxide emissions can be reduced by integrating a solar power generation system. This demonstration resulted in an approximate 17% energy reduction compared with an AC power supply system having the same level of reliability. Also, an evaluation using Data center Performance Per Energy (DPPE) as a performance index of the efficiency of data centers was carried out. The results showed that Power Usage Effectiveness (PUE), one of the sub-metrics of DPPE, improved with the 380VDC power supply system compared with the AC power supply system.
