According to the virtual power plant data protection method and system under the block chain based on the AES algorithm, the AES algorithm and the block chain technology are combined, and dual protection of data encryption and decentralized storage is achieved. And an AES algorithm is embedded in the block chain network, and data in the virtual power plant are encrypted. In the process of the method, firstly, power data generated in a virtual power plant system is collected and encrypted by using an AES algorithm to ensure the privacy of the data in the transmission and storage process; secondly, the encrypted data are stored on a block chain through a block chain network, so that the security and integrity of the data are enhanced by using the decentration characteristic of the block chain; and finally, providing a decryption mechanism to ensure that the user can safely access the data after identity verification. The virtual power plant under the block chain and the AES encryption algorithm are fused, the p
