Abstract: Blockchain technology has been applied to all walks of life since it was proposed. Because of its transparent and secure transaction environment and jointly maintained node information, it has been applied to virtual power plants（VPP） to meet the needs of VPP aggregation of various distributions. The flexible application of the energy supply system with clean and low-carbon energy as the main body, as well as the safe operation and comprehensive defense system of the power system. Starting from the concepts of blockchain and VPP, this paper analyzes the applicability and scenarios of VPP in four aspects: consensus mechanism, encryption technology, distributed storage and smart contracts, and finally analyzes the application of blockchain in VPP applications. The problems encountered are classified and summarized, aiming to improve the flexibility of VPP and distributed power transactions and the portability of data management, and provide ideas for further combining VPP and blockchain to optimize the structure of the power market.
