| The power Internet of Things is regarded as a staged achievement of the rapid development of the smart grid.It combines the related technologies of the Internet of Things to effectively integrate various power equipment and communication infrastructure in the general power grid system,and greatly improves the operation efficiency and work of the power system.It provides the underlying technical support for power generation,distribution,transmission and other links in the power grid,and provides a strong boost for the optimization of the power system.The purpose of this paper is to study how to realize the convenient interaction of power information between the power supplier and the power consumer in the daily power consumption behavior,so as to achieve the purpose of efficient and transparent power business records,and at the same time ensure the data consistency,safety and reliability in the entire process.Since the multi-party power transaction entities are physically distributed and need to record related power interaction services,this paper adopts the blockchain distributed network,and studies the consensus algorithm and incentive mechanism on this basis.While ensuring the traceability and anti-tampering of business data through blockchain technology,multiple parties are encouraged to participate in relevant power activities,and to promote the realization of the grid company’s strategic concept of intelligent power supply,peak regulation and energy saving.This paper aims to study the establishment of a hierarchical on-chain data storage system based on blockchain technology in the power Internet of Things environment,and proposes a scalable electoral efficient consensus mechanism and a trust-based chain The dynamic incentive mechanism is used to ensure the efficiency and safety of the power transaction process,and at the same time,it can improve the enthusiasm of users to participate in the power interactive business,and achieve the goal of reducing both the peak distribution load cost of power grid enterprises and the cost of power users.The main research contents are as follows:(1)Design a primary and secondary two-layer blockchain model as the underlying network architecture,and use a layered consensus algorithm to ensure the efficiency and feasibility of the network itself,and reduce the consensus process through the selection of committee nodes in the secondary blockchain.The user-related data abstracts are stored in the chain to ensure its safety and reliability,and the data information is anchored by using a layered model,and experiments have proved that the performance of the algorithm is better than that of the mainstream consensus algorithm in the power Internet of Things scenario.(2)Design an incentive mechanism for electricity consumption behavior in the environment of electric power Internet of Things.This mechanism generates incentives based on the results of data quantification of user behavior.In a certain incentive period,this quantifiable indicator It is dynamic and will be affected by the user’s on-chain behavior.By giving certain incentives to nodes that contribute to the consensus process,transaction entities can be encouraged to actively participate in distributed energy transactions,improve the efficiency of distributed energy transactions,and form a multiagent,efficient and safe distributed energy transaction scenario. |
