Future smart grid will generate massive multi-state, heterogeneous data in the process of running, obtaining data reliably, real-time analysis, synchronization and processing will bring unprecedented pressure to the grid information system, therefore, it is particularly necessary to migrate the big grid data to the cloud-data center to achieve accurate, real-time synchronization for heterogeneous data. As a starting point, this paper is to solve the processing problem of the future smart grid big data, and by carefully analyzing the related functional requirements of grid data center and comparing with the modeling foundation of traditional relational database, proposes the solution for smart grid data center based on Hbase architecture. Finally, by comparing the performance of MySQL simulation tests, the proposed solution can be well applied on building the future of smart grid data centers and heterogeneous data synchronization, which achieves the purpose of real-time sharing, monitoring, accurate analysis, treatment of the big grid data, so it has broad application prospects in the future smart grid information management system.
