A High Performance Data Storage Method for Embedded Linux Real-time Database in Power Systems

In power systems, extraordinary amounts of data collected from smart grid application systems need to be stored efficiently and effectively in real time. A new data storage method was proposed to deal with the huge data storage problem in embedded Linux operation system. The new method combined the advantages of Linux kernel system customization feature and operation system file management characteristics to fully utilize the hardware resources. The simulation results demonstrated that the proposed method can improve the real-time database system's storage and query performance.
