The emerging blockchain technology has injected new vitality into the energy market, especially the peer-to-peer power trading of microgrid systems. However, with the increase of energy blockchain projects, the difficulty of data communication and value islands between blockchain networks have become open issues. Thus, in this paper, we propose a dynamic adaptive cross-chain trading mode for multi-microgrid joint operation. The novelty is to design a proof of credit threshold consensus mechanism to achieve effective information verification. This consensus mechanism can ensure the adaptive consistency of cross-chain information without changing the existing blockchain architecture of each system. At the same time, we design a corresponding key management interoperability protocol based on RSA algorithm and Chinese remainder theorem, which can realize data transfer and information consensus for cross-chain transactions. The theoretical analysis verifies that the cross-chain communication information is effective and the system is able to protect against the attack of malicious nodes. Finally, a cross-chain simulation experiment is established to analyze the operation efficiency. The result shows that this cross-chain trading takes place within seconds, which basically meets the response requirements for multi-microgrid joint operation.
新兴的区块链技术为能源市场注入了新的活力，特别是微电网系统的点对点电力交易。然而，随着能源区块链项目的增加，区块链网络之间的数据通信和价值孤岛的难度成为了亟待解决的问题。因此，在本文中，我们提出了一种用于多微网联合运行的动态自适应跨链交易模式。新颖之处在于设计了一种信用门限共识机制来实现有效的信息验证。该共识机制可以在不改变各系统现有区块链架构的情况下，确保跨链信息的自适应一致性。同时，我们基于 RSA 算法和中国剩余定理设计了相应的密钥管理互操作协议，实现了跨链交易的数据传输和信息共识。理论分析验证了跨链通信信息的有效性，并且系统能够抵御恶意节点的攻击。最后，建立了跨链仿真实验来分析运行效率。结果表明，这种跨链交易在几秒钟内完成，基本满足了多微网联合运行的响应要求。
