Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples.

[0037] The implementation process of the embodiment of the present invention is shown in figure 1 ,Specifically:

[0038] (1) The user node UP1 needs power in general, and the user node UP2 needs power within m hours in an emergency.

[0039] According to the instantaneous production point and instantaneous power consumption, the sensor nodes SP1, SP2, and SP3 automatically generate electricity prices Price11, Price12, and Price13 for UP1. On this basis, the price is raised by (24-m)*Price according to the urgent demand of UP2 for time m hours, and the sensor nodes SP1, SP2, and SP3 automatically generate electricity prices Price21, Price22, and Price23 for UP2.

[0040] (2) Randomly select three nodes UP2, SP1, and SP3 from all nodes UP1, UP2, ...

Abstract

The present invention is a block chain-based smart grid transaction method and system. The method mainly includes the steps of: sensor nodes automatically generate electricity prices, user nodes automatically create transactions to sensor nodes, and send transaction information and signatures to each Represent the node and verify it, put it into the block, select the primary node and the secondary node, the primary node sends the block and signature to the secondary node, the secondary node performs audit verification, and sends the result to the other secondary nodes for comparison, and the comparison results start To the master node, the master node summarizes all the comparison results and executes the rules on the chain to obtain the transaction fee; the invention solves the problem of intelligent power transmission and can protect the transaction information of the smart grid at the same time, and uses blockchain technology to propose a node consensus algorithm and design distributed data storage The method can prevent the transaction information from being tampered with, encourage grid nodes to participate in the on-chain, and ensure the openness and fairness of the on-chain behavior.

Description

technical field [0001] The present invention relates to the technical field of a smart grid, in particular to a blockchain-based smart grid transaction method and system. Background technique [0002] Smart grids are a key application of the Internet of Things today. In the case of self-generation, the smart grid usually hopes to conduct power transactions with surrounding neighbor nodes in time to avoid repeated power transmission and improve power transmission efficiency. In the traditional smart grid scenario, the data collection base station sends the grid data collected by the wireless sensor nodes to the trusted central node for storage and sharing. Once security issues such as DDOS attacks, single-point failures, and malicious data tampering occur on the trusted central node, the transaction information of the power grid will be destroyed. How to carry out secure transactions in the case of decentralization and form a consensus transaction ledger is a problem that n...
