Study of the key technologies of electric power big data and its application prospects in smart grid

Application of big data techniques in power system will contribute to the sustainable development of power industry companies and the establishment of strong smart grid. This article introduces a universal framework of electric power big data platform, based on the analysis of the relationships among the big data, cloud computing and smart grid. Then key techniques of electric power big data is discussed in four aspects, including big data management techniques, big data analysing techniques, big data processing techniques and big data visualization techniques. Finally, the article presents three typical application examples of electric power big data techniques which are new and renewable energy integration, wind turbine condition monitoring and assessment and data base integrative backup for electric power enterprises.
