摘　　要：综合能源系统(IES)调度中存在难以维护供能主体隐私、难以辨别数据真伪、安全性和可靠性低等问题。文中利用分散式调度方法和区块链中分布式数据存储、智能合约、共识机制、多链扩容和加密技术,提出了包括迭代链、终值链以及数据层、网络层、合约层、共识层、应用层的IES调度构架。该构架以数据层为基础,采用无向联通结构建立主体间的通信网络;在合约层封装基于拉格朗日乘子法的分散式调度模型;在共识层,针对分散式调度的数据一致性,迭代链和终值链分别应用一致性协议算法和拜占庭容错共识机制。算例验证结果表明,所提IES调度构架基于少量通信数据可有效运行,能够防止主体背叛、削弱服务器宕机的影响,提高了IES调度的隐私性、安全性和可靠性。The integrated energy system(IES)has some problems such as the difficulty in protecting the privacy of energy suppliers,distinguishing the authenticity of data,and low security and reliability.In this paper,a dispatching architecture for IES is proposed by using the distributed dispatching method and distributed data storage,intelligent contract,consensus mechanism,multi-chain expansion and encryption technology in blockchain.The dispatching architecture includes iteration chain,terminal value chain,data layer,network layer,contract layer,consensus layer and application layer.The architecture based on the data layer adopts the undirected connection structure to establish the communication network between agents.The decentralized dispatching model based on Lagrange multiplier method is encapsulated in the contract layer.In the consensus layer,for the data consistency of decentralized dispatching,the iterative chain and the terminal chain apply the consistency protocol algorithm and Byzantine fault tolerance consensus mechanism,respectively.The example verification results show that based on a small amount of communication data,the proposed dispatching architecture for IES can operate effectively,prevent agent betrayal,and weaken the impact of server downtime,while improving the privacy,security and reliability of dispatching for IES.
