In order to solve the problems of chaotic control and inefficient maintenance of new energy stations, with the rapid development of big data, cloud platform, internet of things and other related technologies, the construction of new energy monitoring and big data center can improve the management and control ability of new energy stations. At present, new energy big data platforms launched in the industry mostly focus on the intelligent optimization of a single model or station and lack the overall coordination of the group-level new energy business, which makes it difficult to achieve the coordination and integration of various equipment and different systems. In view of the limitations of new energy big data platform construction at the present stage, it has become inevitable for the development of the new energy industry to build a group-level new energy monitoring and big data center to achieve a high degree of integration and sharing of resources and experience. In this paper, relying on the construction background of China Datang Corporation new energy two-level center, sorting out the business process of new energy production equipment management and control and designing the platform technical architecture of cloud-side collaboration, could realize the multilevel fusion of from the bottom perception to the top decision-making and provide guidance for analysis and processing of new energy heterogeneous assets and data and design of group-level new energy big data platform.
