研究目的
To demonstrate the energy savings and carbon dioxide emissions reduction potential of a 380VDC power distribution system interconnected with a solar power generation system compared to an AC power supply system.
研究成果
The 380VDC power distribution system demonstrated significant energy savings (17% reduction) and carbon dioxide emissions reduction compared to an AC power supply system. The system's efficiency was further enhanced by integrating a solar power generation system and using an adaptive power supply management scheme. Future efforts will focus on promoting the deployment of 380VDC power supply systems globally to address data center power consumption challenges.
研究不足
The demonstration was limited to a specific setup at the University of Texas at Austin’s Texas Advanced Computing Center (TACC) and may not fully represent all data center environments. The project period was about one year and eight months, which may not capture long-term variations in energy consumption and efficiency.
1：Experimental Design and Method Selection:
The demonstration involved setting up a 380VDC power distribution system interconnected with a solar power generation system and lithium-ion batteries at the University of Texas at Austin’s Texas Advanced Computing Center (TACC). The efficiency of the data center was measured using the DPPE method, focusing on Power Usage Effectiveness (PUE) and Green Energy Coefficient (GEC).
2：Sample Selection and Data Sources:
The project involved comparing the energy consumption and efficiency of the 380VDC power supply system against a conventional AC power supply system under the same conditions.
3：List of Experimental Equipment and Materials:
A 300-kW rectifier and its distribution panel were used as the main components of the 380VDC power supply system. The system also included a solar power generation system and lithium-ion batteries.
4：Experimental Procedures and Operational Workflow:
The system was operated with an 'adaptive power supply management scheme' to maximize efficiency by adjusting the operating status of the power module based on the power consumption state of the load.
5：Data Analysis Methods:
The efficiency of the power supply systems was compared by measuring input and output powers. The DPPE method was used to evaluate the energy savings performance, focusing on PUE and GEC metrics.
