Description

Technical Field

[0001] The present invention belongs to the field of online transactions of energy storage resources, and in particular relates to an energy storage interactive intelligent terminal based on blockchain technology. Background Art

[0002] In the field of shared energy storage, State Grid Qinghai Province Company has established a blockchain shared energy storage market. Based on the Haixi Multi-energy Complementary Demonstration Project, the project uses blockchain technology to achieve energy storage sharing through the characteristics of immutability and traceability of chain data, and supports the free bidding transactions of new energy and energy storage power station owners. Relying on the shared energy storage model, the energy storage power station of this project not only meets the needs of its own new energy power station, but also provides services for other new energy power stations, maximizing the utilization efficiency of energy storage power stations. At the same time, based on blockchain technology, the resources of Qinghai Province's independent and scattered grid-side, power supply-side, and user-side energy storage power stations are integrated, the grid is unified and coordinated, and the energy storage capacity of each end of the source, grid, and load is fully released, realizing the optimized configuration of energy storage resources with the grid as the hub and the sharing of the entire network, which effectively promotes the local consumption of new energy. The reliable traceability of the power of the energy storage power station guarantees the commercial operation of shared energy storage. Energy storage transaction contracts and execution results are stored on the blockchain platform. The immutable nature of blockchain data ensures the authenticity of the data on the chain. The inherent multi-party participation attribute enables safe and fast data sharing. The data on the chain is open to the government, regulatory agencies and users, and the credibility and use value of the data are further released. Since 2020, relying on the shared energy storage model of blockchain, the Qinghai energy storage market has been initially activated. Domestic power equipment companies and energy storage companies have made early arrangements, and energy storage has played a significant role in boosting the local economy.

[0003] However, the combination of blockchain technology and energy still has many challenges and room for development. Some of these come from the limitations of existing blockchain technology, such as computing power and response speed, data redundancy, network security, and how to interact with traditional platforms; some come from changes in the energy industry's own market and technological development, such as the reform of the power market, the first spot exchange, electric vehicles participating in the power market, and user-side distributed power generation participating in transactions, etc. Many of these require the establishment of corresponding policies and market rules; and there are potential constraints on the combination of blockchain and the energy industry, such as the lack of subjects in smart contracts and legal constraints in the energy industry.

[0004] In the future, as the consensus mechanism of blockchain is improved and perfected, the data processing speed based on blockchain will grow exponentially, thus meeting the application of distributed energy access, interaction and transaction. It is expected that in the future, with the promotion of dual carbon and the acceleration of power market reform, energy blockchain will be deeply applied in the fields of renewable energy, carbon neutrality and transaction, distributed energy transaction, etc. The deep integration of blockchain and energy industry is a major trend in energy development.
