Research On The Model Of Multi-layer Power Transaction Based On Blockchain Technology

With the proposal of “Carbon neutral and Carbon peak”,distributed clean energy is playing an important role in the transformation of power consumption structure.Distributed energy is scattered,small and close to the load.Blockchain’s technical features are in line with distributed energy,so it can be introduced into distributed energy transaction to improve the capacity of consumption.Based on the blockchain technology,a multi-layer power transaction model is established in this paper.It realizes orderly transactions of nodes with different needs.The main research work is as follows:Firstly,the characteristics and types of blockchain are analyzed in this paper.To solve the problem of node decentralization in distributed energy transactions,a multi-layer power transaction model is established based on consortium blockchain.It realizes peer to peer electricity transactions.Secondly,to reduce defaults of nodes in P2 P electricity transactions,a credit incentive mechanism is established in this paper.The fulfillment function and verification reward function are constructed to quantitatively evaluate the performance and the verification of the transaction.By analyzing the power transa ction process involving distributed sources and loads,it is shown that the credit incentive mechanism can promote nodes to actively complete their contracts and improve the consumption of distributed energy.Thirdly,in order to realize orderly transaction and the clearing of power in the electricity market,a P2 P electricity transaction mode is established in this paper.By building a non-cooperative game model,the behavior and interests of nodes is quantitatively analyzed in game step.Design a reasonable matching method to help untraded nodes find a reasonable transaction objects in clearing step and improve transactions.By analyzing the transaction process of power supplier nodes and consumer nodes,it is shown that the P2 P electricity transaction mode promotes the clearing of distributed power and improves the consumption of distributed energy.Finally,the needs of the platform are analyzed in this paper.At the same time,the smart contract and the consensus mechanism are designed,which are the key parts of the platform.A P2 P electricity transaction system is built based on Hyperleder Fabric,it provides a safe and reliable transaction platform for the distributed nodes.The research of the paper show that the multi-level power transaction model based on blockchain technology can realize distributed energy transactions.At the same time,it can help nodes reduce their defaults and transact orderly,thereby distributed energy consumption can be improved.
