摘要:

为保障配电网稳定运行,运行异常与处理措施的信息交互通常由操作员完成,但这种方式容易受操作员的主观性影响,出现处理措施与运行异常不匹配的情况,并且缺少对交互过程信息安全的保障。因此,提出一种基于区块链的配电网异常管理网络模型——异常管理区块链网络(EMBN),以及一种改进的配电网三道防线模型。首先,根据区块链防篡改和可追溯的特性,构建异常索引区块链(AIB),根据区块中的最新信息寻找合适的措施处理运行异常;其次,构建异常交互区块链(EIB)对运行异常和处理措施的交互过程进行监控,确保处理措施的实施;最后,将EMBN应用于传统配电网的三道防线,并结合智能合约实现配电网的自适应检测和异常应对。仿真结果表明,面对配电网的复杂环境,EMBN可以匹配处理措施与运行异常,不受操作员主观性的影响;相较于传统配电网,EMBN在信息交互的信息安全方面具有一定的优越性。

Abstract:

The information interaction between operation anomalies and treatments is usually completed by operators to ensure the stable operation of distribution networks, but it is vulnerable to the subjectivity of operators, resulting in the mismatch between treatments and operation anomalies, and the lack of guarantee of information security for the interaction process. Therefore, a blockchain-based network model for distribution network exception management, Exception Management Blockchain Network (EMBN), was proposed, as well as an improved three-line defense model for distribution network. Firstly, according to the tamper-proof and traceable characteristics of blockchain, an Anomaly Index Blockchain (AIB) was constructed, and appropriate treatments were found to solve operation anomalies based on the latest information in the block. Secondly, an Exception Interact Blockchain (EIB) was constructed to monitor the interaction process of operation anomalies and treatments, and ensure the implementation of treatments. Finally, the EMBN was applied to the three-lines of defense in traditional distribution network, and the intelligent contract was combined to realize adaptive detection and anomaly response of the distribution network. Simulation results show that, facing the complicated distribution network environment, EMBN can match treatments and operation anomalies without the influence by subjectivity of operators; compared with the traditional distribution network, EMBN has the advantage in the information security of information interaction.
