Research On Data Security Sharing Of Power Market Based On Blockchain

With the development of energy Internet,more and more distributed generation access to power grid,forming a variety of heterogeneous energy networks.However,in power market,the centralized management of different energy networks cannot effectively exchange information,which seriously affects the complementary ability of heterogeneous energy and leads to the phenomenon of energy island.In this paper,firstly,we investigate the power market,understand the industry pain points,summarize the relevant research directions at home and abroad,determine the energy blockchain improvement scheme of power market,and deeply study the blockchain related technologies,including consensus mechanism and cross-chain technology.Secondly,the model of energy data exchange based on the cross-chain technology of blockchain is designed,and the function of the smart contracts in the contract layer is designed.The model stipulates that the same kind of energy is traded in the chain,and the heterogeneous energy is distributed in different energy chains.Thirdly,in order to trade between energy networks more effectively,the performance of the model is optimized.In the same chain,based on Boneh-Lynn-shacham,the signature mechanism is improved,the consensus algorithm is optimized,and the pledge mechanism is introduced.In the heterogeneous chain,the heterogeneous energy nodes are assigned to different energy sub chains,the cross-chain energy transaction is carried out through the relay chain,the cross-chain routing and the fisherman machine are introduced.Finally,the feasibility,intra-chain performance and cross-chain performance of the model are simulated by setting up an experimental environment.The experimental results show that the feasibility of the model and the correctness of the smart contracts.The energy data transmission efficiency in the chain and the cross-chain throughput are greatly improved,which proves the superiority of the system compared with the existing systems,and provides a reference for the application of cross-chain technology in energy internet.
