Blockchain-based New Power System Plant-grid Coordination Sunshine Service and Scheduling Technology

Scheduling technology is essential in the coordination of new power systems, but the traditional power system still has problems such as low accuracy of supply and demand matching and long dispatch response time when carrying out grid-plant cooperative scheduling. The purpose of this paper is to use blockchain technology to optimize the scheduling technology and scheduling strategy in the new type of power system plant-grid coordination, so as to make it better to meet the latest demand for power system scheduling, and to ensure the stable and reliable operation of the power system. A distributed consensus mechanism is first applied in this paper to solve the insertion problem faced by centralized scheduling, and uses a Bloom filter to design a distributed power source peer-to-peer transaction mechanism; then, combining the immutability and traceability of blockchain, a new collaborative scheduling mechanism for power systems was designed; then the role of blockchain in promoting market-oriented operation of the power system was elaborated. Finally, the effectiveness of applying blockchain technology to the new type of power system grid coordination sunshine service and scheduling technology was verified. Through empirical research, it has been found that when the matching time of power supply and demand reaches 25 hours, the accuracy of traditional methods for matching is only 81.57%, while the method proposed in this paper can achieve ${9 0. 6 3 \%}$. At the same time, the dispatch response time of the power system under the method proposed in this paper is significantly shorter than that of the power system under traditional methods. The study proves the value of the application of blockchain technology on the new power system plant-grid cooperative scheduling, which provides more methods to guarantee the stable operation of the power system and promote the better development of the power market.
