Abstract

Abstract:

With the rapid development of clean and renewable energy industry, the existing energy structure is difficult to meet the needs of energy production and market. An energy industry innovation is imperative. As a promising development direction of the next generation energy infrastructure in academic and industrial circles, energy internet has been widely concerned. Its basic characteristics of openness, interconnection, equivalence and sharing provide a rich vision for future energy development. However, the existing matured information technology solutions cannot fully satisfy the requirement of energy internet from design idea to project implementation. As a rapid development technology, blockchain has the characteristics of distribution, equality, security and traceability, which is highly consistent with the design idea of energy internet, and is expected to become the key technology for the implementation of energy internet. Energy blockchain is the product of the combination of blockchain and energy industry, which can provide security and value support for all levels of energy internet. By positioning the key technologies of power trading blockchain in the energy internet, this paper summarizes the research progress of the current power trading blockchain in the aspects of consensus mechanism, transaction and smart contract design, security mechanism and other fields of technology. Combined with the research status, this paper discusses and analyzes the problems existing in various technical fields and the possible future, and provides a reference for further research and implementation of energy blockchain.

Key words: blockchain, energy internet, power trading, consensus mechanism, smart contract, security
