The power system covers a wide area and network instability in some areas causes data to be lost or damaged during transmission, while storing data in the cloud means users have less control over their data, increasing the risk of sensitive data leaks. Therefore, considering the integrity and privacy of data storage, a distributed storage method for privacy protection of power energy data is proposed by introducing cloud-edge collaborative technology. Considering the operating environment of cloud-edge collaborative technology, the distributed storage space is constructed. Cloud edge collaboration utilizes the centralized management capabilities of the cloud to ensure data consistency, while local storage on the edge provides fast data access and recovery capabilities. Web crawler technology is used to automatically collect data related to power energy and provide data support for subsequent data storage. The symmetric encryption method is introduced, and the plaintext key is generated by combining feature matching. The plaintext and encryption key are used together to symmetrically encrypt the collected electric power energy-related data, and the private key is obtained by asymmetric encryption method to realize hierarchical encryption of electric power energy data. The cloud edge collaboration technology is used to parallel dispatch power energy privacy data, and the distributed storage task of power energy data privacy protection is realized by encrypting data written in the selected storage space. Through the performance test, it is concluded that the average privacy data loss of the proposed storage method is 0.5MB and 1.3MB respectively in the non-attack scenario and the attack scenario. The average tampering rates were 0.5% and 0.6% respectively. The data storage throughput reaches more than 400MB.
