Application of Load Balancing Technology Based on Dynamic Migration in Wide Area Measurement Data Storage

With the increasing number of technology, Wide area measurement plays an important role in real-time analysis of low frequency oscillation, transient stability control, voltage phase angle and amplitude measurement in modern smart grid. Wide area measurement has huge amount of data and how to store data is an important issue in wide area measurement. This paper presents the storage method of wide-area measurement data, studies the load distribution, adopts the Magician dynamic migration framework, which is developed based on Xen, and proposes the hierarchical copy algorithm and compression algorithm to optimize the mass data storage in wide-area measurement. Through the research, the problem of excessive data in wide-area measurement can be better solved, the reasonable storage of wide-area measurement data can be realized, and the role of wide-area measurement in smart grid can be better played.
