A Blockchain-Based Microgrid Measurement Data Storage and Tampering Detection Framework

With the rapid development of distributed power generation and microgrids, secure storage of microgrid measurement data becomes an imminent issue. In order to defend against cybersecurity threats, a microgrid measurement data storage framework should not only ensure the integrity and traceability of the stored microgrid measurement data, but also be able to detect any malicious data tampering. In this paper, a microgrid measurement data storage framework based on Hyperledger Fabric, a blockchain technology, is proposed and implemented, on top of which a data tampering detection method based on the uniqueness of the transaction number (TxId) and the Strong Collision-Resistant of hash theory is developed. Case studies show that the proposed framework can well meet the requirement of data storage traceability, transparent sharing, and tampering resistance, and the requirement of automatic data tampering detection, which provides a new research idea and direction for the future study in microgrid measurement data storage.
