Research on the transaction mode and mechanism of grid-side shared energy storage market based on blockchain

Energy storage has high application value in the power system, especially in the field of auxiliary services, but the transaction mechanism and process are not yet perfect. Considering the advantages of security and transparency of blockchain technology, this article combines blockchain with energy storage auxiliary services and proposes a blockchain-based grid-side shared energy storage market transaction model and mechanism. This article first introduces the concept and application status of blockchain, and compares the advantages of blockchain technology applied to power transactions. Combined with the existing policies and market rules, the research on the participation of energy storage in auxiliary services was carried out, and the market mechanism for the participation of energy storage in peak and frequency modulation auxiliary services was designed. Finally, a blockchain-based energy storage market-oriented transaction model and mechanism is proposed to improve the flexibility of the power system and promote clean energy consumption.
