Research On Retail Trading Mechanism And Model Of Prosumers Based On Blockchain Technology

With the advancement of the marketization process,the power industry has continued to cater to market demand and actively adjust its own power trading mechanisms and models.At the same time,the continuous innovation of intelligent sharing technology has promoted the development of the marketization of the power industry from shallow to deep.However,the mode and power retail transaction's mechanism of power retail transactions between the most object-oriented,complex and wide-ranging prosumers are the focus of power reform,and few studies have been conducted.Therefore,the research on the mode and the mechanism of the electricity retail transactions among prosumers has the characteristics of the times and the practical significance.So,it is an urgent research topic about how to guide the prosumers to participate actively in the distribution of unbalanced power consumption on the distribution network,and to take into account the economic and social benefits of the social market.This paper studies the ways,mechanisms and models of power retail transactions between prosumers under the premise of the opening of the power distribution market.The main research work is as follows:(1)The development trend of blockchain technology and its application in various industries are analyzed.The application process of financial transaction based on blockchain technology is summarized.Combined with the application of blockchain technology in power sharing projects,the general information-physical process of power retail transactions between prosumers is constructed,and a quantitative model based on blockchain technology for power trading applications is proposed.(2)Constructing a communication architecture for the decentralized power retail transaction,from the two perspectives of the survivability and invulnerability of the transaction communication network,the new trustworthy reliability of the electricity transaction between prosumers is studied.The reliability of transaction communication based on the blockchain technology framework is quantitatively analyzed by an example.(3)Considering the guidance of the prosumers to actively participate in the distribution of power imbalance in the distribution system,by classifying the prosumers,setting the economic constraints of responding to unbalanced electricity,and constructing the conditions for the prosumers to participate in the power response,this paper proposes the elastic electricity price and environmental protection electricity price that can couple the electricity demand of the distribution system as a tool to guide the production and consumption of users to participate in the market response,and verify its effectiveness.(4)Combining the power distribution constraints of the power distribution system,formulating the physical constraint indicators of the power transaction verification smart contract embedded in the blockchain script,the mechanism of power retail transaction based on blockchain technology is proposed.It includes the basic mechanism of transaction,the process of mechanism verification and the process of user response trading mechanism.(5)This paper analyzes the economic and environmental protection benefits of power retail transactions between consumers and producers from the perspective of buyer,buyer's market and continuous time period respectively by adopting the VCG bidding mode and the equilibrium clearing mode of"price first,time first" multilateral bidding mode.
