The diversity and heterogeneity of distributed energy resources pose many challenges to data security and sharing during the aggregation process of resources. Therefore, exploring the storage model applicable to distributed resource aggregation and constructing the corresponding secure sharing system is necessary. To address this issue, this paper proposes a distributed storage scheme based on the Interplanetary File System (IPFS). The proposed model provides secure data storage and access control for distributed resource aggregation through proxy re-encryption and smart contracts. The experimental results and performance analysis show that the scheme can effectively avoid the problems of increased node storage pressure and blockchain expansion due to storing all data on the chain. The model can significantly reduce the maintenance and storage costs of the blockchain and increase the speed of data processing. At the same time, this model allows authorized users to share data securely, effectively achieving data privacy security for various distributed energy sources.
