Description

Block chain consensus method applied to power resource sharing network
Technical Field
The invention relates to the technical field of block chain consensus, in particular to a block chain consensus method applied to a power resource sharing network.
Background
With the development of society, the traditional power grid gradually develops towards the smart power grid, and the development of the smart power grid causes uncertain power demand, which causes unpredictable fluctuation of the power generation amount of the traditional power generator and the flow of the power grid system. In order to reduce the load fluctuation level of the power grid, progress optimization strategies for sharing electric energy by various power grid users are endless, and due to the fact that various problems such as trade orders, trade users and management accounts are involved in the electric power resource trading process, the time consumption and flexibility of the trading process between the users and the power grid are caused. Therefore, in order to encourage grid users to achieve demand responses in their own interest, blockchain techniques are combined with distributed energy trading networks.
Blockchain technology was originally used in cryptocurrency "bitcoins" without third parties as a ledger with distributed and immutable features, above which transactions were transparently traceable. The consensus protocol is a key part of the blockchain technology, and achieves that the non-falsifiable and non-repudiatable ledger records are completed without a third party. Due to the decentralization and high safety of the block chain, the block chain technology is applied to reliably and credibly manage data in the information sharing and resource transaction processes in the power grid scene. The consensus algorithm as a key technology of the block chain plays a crucial role in the efficiency and safety of the power grid system. With conventional consensus algorithms, for example, workloads prove difficult to compute when mining, so that trading speed is slow; the equity certificate utilizes the equity mastered by the participants to replace the ore digging operation, but easily causes the power to be mastered in the hands of a few fixed participants; most BFT type consensus algorithms have poor expandability and are difficult to increase users in large quantities. Therefore, the traditional consensus algorithm cannot meet the requirements of the power grid on efficiency and safety, and a new lightweight consensus mechanism suitable for the power grid system is needed.
For power resource sharing networks applying blockchain technology, efficiency and security are important issues that now need to be addressed. As trading users of the power resource sharing network have limited resources, a lightweight consensus algorithm is required to improve the efficiency of the power resource sharing network. Meanwhile, accurate implementation of transactions in the power resource sharing network and requirements of non-tampering require a consensus algorithm capable of preventing power concentration.
Based on the above, how to provide a lightweight block chain consensus processing method for a power resource sharing network to achieve reliability and security of the power resource sharing network is a technical problem to be solved.

The leader selects the deals meeting the preset voting number as legal deals according to the voting information, the legal deals are packaged into blocks, and the blocks are used as preselected blocks to be broadcast to the alliance network; other alliance committee nodes except the leader verify the preselected block.
If the verification is passed, the leader connects the preselected block as a final block to the block chain, the electric energy distribution node receives the final block and broadcasts the final block to the public network, the consensus of the round is completed, and a reward and punishment mechanism is triggered to win the incentive mechanism; based on the reward mechanism, the verifier nodes, the leaders and the voting alliance committee nodes corresponding to the current round of legal transaction are rewarded, and specifically, the initial random trust values of the corresponding verifier nodes are improved, namely
