The future power grid will be a highly automated, intelligent power grid, such a large, complex system from power generation, transmission to change, distribution, power process will always generate massive amounts of power information and equipment operation status data, which requires a strong information processing platform as a support, and this platform should have a reliable storage of massive data, accurate analysis, real-time synchronization update and sharing functions, especially audio and video and other heterogeneous data analysis and processing, cloud computing technology has a unique advantage in big data processing, the cloud computing technology will be used in the paper to integrate the cloud computing technology, information platform research on smart grid. This platform should have the functions of reliable storage, accurate analysis, real-time synchronous updating and sharing of massive data, especially the analysis and processing of heterogeneous data such as audio and video. Cloud computing technology has unique advantages in big data processing, and the paper introduces cloud computing technology into the construction of future smart grid information processing platform, discusses the functional requirements of the future smart grid information processing platform, compares the many bottlenecks of the current grid information processing platform, and proves that cloud computing technology can be applied to the future smart grid information processing platform, which can help to improve the efficiency of the information processing platform. It proves the feasibility of applying cloud computing technology to the future smart grid information processing platform.
