Research On Energy Trading Scheme Based On Alliance Blockchai

Energy users using wind turbines,solar power generating,and energy storage devices have transitioned from consumers to consumers as a result of the development of energy Internet technologies.They’ve improved their ability to transmit energy to other countries and created a distributed energy system that is geographically dispersed.Although it is convenient for energy management and setting if the typical centralized energy trading mode is used,it has significant drawbacks.First,the centralized organization can read users’ private data straight from the server,such as energy trading data,and there is a single point of failure.Second,distributed energy nodes are characterized by intermittency(such as wind and photovoltaic),randomization(outside the power generating plan),and mobility(new energy electric cars),all of which make traditional centralized energy trading difficult to dispatch and distribute.Third,in a highly market-oriented competition environment,every energy consumer is a rational individual seeking to maximize their own interests,resulting in fierce rivalry in the distributed energy trading market,which is not conducive to the development of the energy Internet.As a result,achieving safe,reliable,and efficient transactions between dispersed energy nodes is a critical problem that must be solved as energy Internet technology develops.In this regard,the research contents of this paper are as follows:(1)Energy trading scheme based on consortium blockchain and game theory.Firstly,an energy transaction scheme suitable for distributed energy nodes is designed based on blockchain technology to realize direct transactions between energy nodes.Secondly,there is competition among a large number of plug-and-play distributed energy nodes in the energy Internet,which leads to the conflict of interests of energy nodes.In this regard,game theory is introduced to study the transaction interaction of multiple distributed energy entities to balance the interests of each energy subject,to achieve the optimal allocation of resources.Finally,the proposed scheme is verified by experimental analysis.(2)Data security sharing and incentive contract scheme for energy trading.Firstly,a digital signature scheme suitable for secure interaction between energy nodes is designed to ensure the correctness of transaction information and the reliability of the identity of energy nodes during the interaction process.Secondly,an incentive mechanism is designed based on smart contracts to encourage energy nodes to honestly participate in transactions and increase the enthusiasm of users to participate in transactions.Finally,according to the idea of Raiden Network,an off-chain fair transaction protocol is proposed to improve the throughput and fairness of transactions.(3)A regulated and privacy-preserving scheme for energy trading.Firstly,the hiding of the transaction amount is achieved through Pedersen commitment and Bulletproof range proof,which makes transaction information unavailable to users other than both parties to the transaction.Secondly,the authenticity of regulatory notes is ensured by using El Gamal encryption and zero-knowledge proof technology,which enables users to monitor and audit transactions without performing open commitments.Finally,a multi-base decomposition method is proposed to improve the encryption and decryption efficiency of users and supervisors.Experiments and security analysis show that the scheme can satisfy transaction privacy and supervision.
