Consortium Blockchain Based Data Aggregation and Regulation Mechanism for Smart Grid

Flexible regulation of smart grid is vital for grid operation. This paper proposes a smart grid data aggregation and regulation mechanism based on consortium blockchain, and its signcryption algorithm can be applied to multidimensional data acquisition and multiple receivers in the consortium blockchain. In the process of regulation, the control center, the grid operator, and the equipment supplier receive fixed-height blocks from the blockchain and obtain plaintext from the decryption. Each receiver analyzes the multidimensional data and formulates corresponding control policies for individual users. Grid operators implement user power regulation by feedback on smart contracts. The security analysis and performance comparison show that the proposed scheme has advantages in computing and communication costs while meeting security requirements for confidentiality and data integrity.
