As the technical basis of Bitcoin, block chain has the characteristics of decentralization , openness and transparency. In order to promote the development of security and openness of power trading system and solve the trust problem among participants in power market,a new research direction of power trading method based on block chain is proposed. Therefore,this paper outlines the block chain,explains the definition and characteristics of block chain in detail,discusses the application of block chain in power trading system,and summarizes the challenges faced by block chain technology in power trading system.
Block chain technology is one of the optional technologies for the realization of intelligent power transactions on the residential side, and the specific transaction process is lacking research. Based on the composition of the block chain and its technical characteristics, this paper proposes a typical transaction flow for market participants in the electricity transaction under the environment of the residential side open electricity market based on block chain technology. According to the needs of power trading, the power trading using block chain technology is divided into 7 steps and abstracted separately. Finally, the power transaction based on block chain technology is analyzed, and the transaction process is further explained in combination with the case, which provides a reference for the introduction of new technologies for the design of ubiquitous power internet of things power transactions.
