In order to reduce the fire risks and hidden dangers caused by battery aggregation, and improve the safety of energy storage system applications, this paper proposes a decentralized wind storage integrated collaborative control strategy and its demonstration application research. The decentralized energy storage system of the wind farm described in this article includes three subsystems: 1) a decentralized energy storage unit with "one machine, one storage", 2) a signal transmission and communication system for decentralized energy storage equipment, and 3) a wind power decentralized energy storage collaborative control system. On the basis of completing the system hardware and software, this article presents the architecture of a decentralized energy storage collaborative control system and develops an overall control strategy based on the principle of frequency modulation priority. Finally, this article will demonstrate the application of the decentralized energy storage system in the Dayou wind storage project. The demonstration application test results show that, taking the 2021 annual power assessment of Dayou Wind Power as an example, analyzing the benefits of decentralized energy storage on power prediction on an average monthly basis. Da You has an installed capacity of 126.3MW, with a short-term assessment of 228600 yuan. After adding energy storage, the assessment cost can be reduced by 1.8 million yuan per year. This not only meets the requirements of decentralized energy storage layout and centralized monitoring, but also reduces control system interfaces, providing demonstration, reference and guidance for the development of renewable energy+decentralized projects, and has important application value.
