Premium Power Supply Scheme for Data Center With SMES and DG Integration

In order to meet the composite demand of premium power supply and energy consumption reduction of data centers, this paper presents a reliable 2N power supply architecture for data centers including superconducting magnetic energy storage systems (SMES). The architecture features two distinct DC voltage levels: 575 V and 240 V. The 575 V DC bus integrates distributed generation (DG) and uninterruptible power supplies (UPS) to enhance energy efficiency, while the 240 V DC bus interfaces directly with the data center. Additionally, an energy management strategy is devised for this power supply configuration, and a control approach for SMES based on event-triggered mechanisms is proposed to guarantee uninterrupted power supply to the data center. A 2N architecture power system is modelled using MATLAB/Simulink, and the results validate the effectiveness and reliability of the proposed approach.
