Application Technology of Big Data in Smart Distribution Grid and Its Prospect Analysis

In allusion to the application of big data in smart distribution grid, the current situation and feature of big data in smart distribution grid is analyzed and the data relation network is teased out at first. Secondly, some key technologies involved in big data application of smart distribution grid, such as big data storage and processing, and big data analytics, are expounded, and on the basis of that,data value chain and "aircraft type" theoretical framework for big data application is proposed. Finally, in aspects of electricity demand forecasting and coordinated scheduling of power supply and load, development trend analysis and optimal planning of smart distribution grid structure, smart power utilization and network dissipation reduction, the application prospect of big data is analyzed, and the application roadmap is presented.
