基于链上链下协同的多元分布式储能交易机制

Multi-distributed Energy Storage Trading Mechanism Based on On-chain and Off-chain Collaboration

随着能源市场改革有条不紊地进行,电力市场呈现出多元、开放、竞争的发展趋势。但区块链技术应用于储能交易时仍然存在交易可靠性差、数据冗杂、能源单一等弊端。针对上述问题,本文基于联盟链建立多元分布式储能交易平台,提出一种基于链上链下协同的多元分布式储能交易机制。首先,针对分布式储能交易中的违约行为建立节点信誉值评估模型。其次,设计基于链上链下协同的多元分布式储能交易机制,储能传输服务方验证链上网络层交易用户签订的智能合约有效后,进行链下物理层储能传输。再次,将联盟链和云服务器结合建立数据索引,将历史储能交易数据存放至云服务器。最后,基于Fabric网络搭建多元分布式储能交易平台,仿真算例验证本文所提交易机制可以在保证储能交易的安全性和可靠性的同时,提高交易效率,满足了多元分布式储能交易场景对交易可靠、数据灵活和储能多元等的要求。

With the orderly reform of the energy market,the electricity market has also shown a diversified,open,and competitive development trend.However,when blockchain technology is applied to energy storage transactions,there are still disadvantages such as poor transaction reliability,redundant data,and single energy.Given the above problems,the establishment of a multi-distributed energy storage trading platform based on the alliance chain is studied,Firstly,a node reputation evaluation model is established for the default behavior in distributed energy storage transactions.Secondly,a multi-distributed energy storage transaction mechanism based on on-chain and off-chain collaboration is designed.After the energy storage transmission service party verifies the validity of the smart contract signed by the on-chain network layer transaction user,the off-chain physical layer energy storage transmission is carried out.Thirdly,the alliance chain and the cloud server are combined to establish a data index,and the historical energy storage transaction data is stored in the cloud server.Finally,based on the Fabric network,a multi-distributed energy storage trading platform is built.The simulation example verifies that the trading mechanism proposed in this paper can improve the transaction efficiency while ensuring the security and reliability of the energy storage transaction,and meet the requirements of the multi-distributed energy storage transaction scenario for transaction reliability,data flexibility,and energy storage diversity.
