摘要: 为了节能环保,减少数据中心机房建设成本,将新能源引入供电系统,形成绿色数据中心供电系统。介绍了现有的数据中心供电方式,分析了传统供电方式的不足。设计了含光伏发电、储能装置、交流电网、负荷的数据中心直流供电系统。根据母线电压稳定控制,将系统的运行划分为8种工作模式,结合系统运行模式和本地信息对各变换器进行相应控制,针对绿色数据中心直流供电系统提出相应的能量控制策略,协调控制系统的有功功率,保证系统供电可靠性。在Matlab/Simulink软件中分别对系统在并网和孤岛运行状态下构建了仿真模型,仿真结果验证了上述控制策略的可行性。

Abstract: To save energy and protect environment and reduce the apparatus room construction cost of data center, this paper introduces new energy into the power supply system and establishes the power supply system of green data center. This paper introduces the existing data center power supply modes, analyzes the deficiency of the traditional power supply mode, and designs DC power supply system of data center including PV generation, energy storage device, AC grid and load. On the basis of bus voltage stability control, the system operation is divided into eight operating modes to control the corresponding converter according to system operating mode and local information. This paper proposes the energy control strategy for the DC power supply system of green data center, which can ensure the reliability of power supply by coordinating and controlling the active power. Via Matlab/Simulink software, the simulation models of system are built respectively under grid-connection and grid-disconnection operations, the result of which verifies the feasibility of the proposes control strategy.

Key words: green data center, DC power supply, energy saving, coordinated control, reliability
