Method and Application of Power Grid Model Management based on Blockchain

The power grid dispatching control platform has established a set of unified model structure, and formed a complete set of whole network model data maintenance process. However, the existing model maintenance methods have long model synchronization and subscription process and poor timeliness, so it is difficult to ensure the consistency of the model; In the process of synchronization, collection and subscription, there is a lack of supervision mechanism, which may lead to problems such as incorrect deletion and modification, and it is difficult to quickly locate the operation time, personnel and other information; In addition, due to the low frequency of periodic backup of model data, it is difficult to accurately obtain the whole network model data at a specific historical moment, and it is difficult to support the data requirements of big data analysis and mining applications such as power grid post accident assessment and fault warning. In this paper, a power grid model management method based on blockchain is proposed. By using the characteristics of blockchain, the tamper proof and traceability of power grid model are realized, and the real-time version management of model data is realized. The effectiveness and efficiency of this method are verified in the application.
