Abstract

Abstract:

With the deep integration of the energy revolution and the digital revolution, it has become an inevitable trend for big data to help the innovation and development of the energy internet. The storage and utilization of traditional energy data is an enterprise-centered information island, lack of efficient and reliable data sharing mechanism, which directly hinders the information mining of energy big data. In response to this problem, this paper proposes a blockchain-based knowledge sharing model for big data of energy internet, in which the cloud-side collaboration-based knowledge extraction architecture of energy big data solves the problems of difficult data privacy guarantee, low mass data transmission efficiency and poor data security. The architecture proposed in this paper can support the rapid and efficient realization of knowledge sharing between entities under the background of the energy internet. It has the characteristics of high transparency, high reliability, and traceability, and it provides a new solution for the knowledge sharing of energy big data.

Key words: alliance blockchain, energy big data, knowledge sharing, cloud-edge collaboration
