基于区块链的电力市场交易系统改进共识机制设计

Design on Improved Consensus Mechanisms for Power Market Transaction System Based on Blockchain

为满足电力市场交易监测需求,解决现有区块链技术中共识机制与电力市场交易业务不匹配的问题,提出了一种面向市场交易监测的共识机制。共识机制是区块链技术的核心,各节点将按照约定的共识机制对区块交易数据校验,只有满足共识机制要求的区块数据才能存入区块链。基于电力市场交易中出清模型特征,提出了一种基于拉格朗日函数的共识机制。并充分考虑市场交易流程,将区块链数据处理与市场出清过程紧密结合,设计了以该改进共识机制为核心的市场交易业务流程。基于开源区块链平台的测试系统表明,本文所提出的共识机制具有更高的处理能力,同时更符合电力市场交易特点,能够提升市场运营机构业务透明度。

In order to meet the monitoring demand in power market transaction and solve the mismatch between the existing blockchain technology consensus mechanism and power market transaction business,an improved consensus mechanism for power market transaction is proposed.Consensus mechanisms are the heart of blockchain technology.Each node will verify the block transaction data according to an agreed consensus mechanism,and only block data that meets the requirements of the consensus mechanism can be deposited into the blockchain.A consensus mechanism based on the Lagrangian function is proposed based on the clearing model features in power market transactions.The business process of power market trading with the improved consensus mechanism as the core is designed to closely integrate blockchain data processing and market clearing process by fully considering the characteristics of electricity market transaction.The test system based on the open source blockchain platform shows that the consensus mechanism proposed in this paper has a higher processing capacity and is more in line with the characteristics of power market transactions,which can enhance the transparency of the business of power market operators.
