摘要/Abstract

摘要：

随着清洁可再生能源产业的迅速发展,现有的能源架构难以满足能源产消的需要,一场能源行业的革新势在必行。能源互联网作为一个学术与工业界看好的下一代能源基础设施的发展方向,受到广泛关注,其开放、互联、对等、分享的基本特征为未来能源发展勾勒出一个丰富的愿景。然而,现有成熟的信息技术方案从设计思想到工程实施无法全面满足能源互联网的特征需求。区块链作为一种正在快速发展的技术,具有分布式、平等、安全、可追溯等特性,与能源互联网的设计思想高度契合,有望成为能源互联网落地的关键技术。能源区块链是区块链与能源行业结合的产物,其可以为能源互联网的各个层面提供安全保障和价值支撑。文章通过定位能源互联网中电力交易区块链中的关键技术,综述了现今能源电力交易区块链在共识机制、交易与智能合约设计、安全机制和其他领域技术等方面的研究进展,并结合研究现状进行了讨论与分析,探讨了目前各项技术领域存在的问题,以及未来可能的研究方向,为能源区块链的进一步研究与落地提供参考。

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
