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。
In order to save energy and environmental protection, reduce the data center building cost, the new energy into the power supply system, the formation of green data center power supply system. The existing data center power supply mode is introduced, and the insufficiency of traditional power supply mode is analyzed. A data center DC power supply system with photovoltaic power generation, energy storage, AC grid and load is designed. According to the busbar voltage stability control, the operation of the system is divided into eight working modes, and the converters are controlled according to the system operation mode and local information. Corresponding energy control strategies are proposed for the DC data center DC power supply system to coordinate the control system Active power to ensure system reliability. In Matlab / Simulink software, the simulation model of the system is established under the grid-connected and islanding operation respectively. The simulation results verify the feasibility of the above control strategy.
