Yinlong's megawatt-level lithium battery energy storage technology passed the acceptance of the Ministry of Science and Technology

Recently, Shenzhen Baoqing battery energy storage station using Yinlong titanium technology ushered in the sixth anniversary of safe and stable operation. This energy storage station is my country’s first megawatt-level lithium-ion battery energy storage station and is also a national 863 project and China Southern Power Grid Corporation's key technology project—the key technology research and pilot demonstration project of 10 MW battery energy storage station. The six-year successful operation indicates that my country has studied, mastered and successfully applied the key technology of megawatt battery energy storage. International level of technical indicators In January 2010, Yinlong New Energy and Peak-shaving and Frequency-modulation Power Generation Company began to organize scientific research on key technologies of megawatt-level battery energy storage. The 1 MW battery energy storage subsystem was launched on January 2, 2011. It was officially connected to the grid on the 13th, and the current capacity has been put into operation up to 18 MWh. The project relies on the project to apply for 47 patents, prepare 1 IEEE international standard, 7 national standards, 7 industry standards, and publish 57 papers. (Shenzhen Baoqing Energy Storage Power Station) In the past six years of project operation, operation and maintenance personnel have actively explored the development and application of key technologies for large-capacity battery energy storage systems without relevant experience to learn from, accumulate relevant experience in operation and maintenance, and carry out scientific research experiments. The project team innovatively proposed an integrated design method for energy storage systems covering energy conversion systems, battery systems, battery management systems, and monitoring systems, and designed an overall method for energy storage power stations with large-capacity lithium-ion batteries (Yinlong titanium batteries), and developed The world's first 10KV high-efficiency (98.3%), large-capacity (2MW), and fast dynamic response (less than 2ms) energy storage energy conversion device, which improves the consistency of the multi-stage series and parallel of the battery, and improves the parallelism of the energy storage system. Network efficiency has formed a series of major innovative achievements in the field of energy storage, and related achievements have reached the international leading level. The operation results show that the operation of the energy storage power station is safe and stable, the response time of the energy storage system is not more than 10ms, and the overall efficiency can reach 90%. The efficiency of the energy conversion system can reach 98.3%, and it can realize multiple application modes such as peak regulation, frequency regulation, voltage regulation, and island operation. The key technical indicators are all superior to the advanced level at home and abroad. The core technology is highly recognized. At present, the project has passed the final acceptance of the Ministry of Science and Technology. The expert group spoke highly of the results of the project and believed that the results of the research and development of the project fully reflected the intent of the 863 project. The results are suitable for my country’s national conditions, innovative and forward-looking, and provide strong technical support and support for the rapid promotion of the healthy development of the energy storage industry. Demonstration use. In January 2017, Yinlong New Energy attended the work meeting of the 2016 Guangdong Science and Technology Award Review Committee. Won the 2016 Guangdong Science and Technology Second Prize, and Yinlong New Energy, as a project participant, won the 2016 my country Southern Power Grid Corporation's first prize for scientific and technological progress. Staged breakthroughs in commercialization Looking at the world, the development of energy storage has become my country's established direction, whether it is from the perspective of seizing the world's technological commanding heights or from the perspective of improving the atmospheric environment. Energy storage technology has become an important organic component of future clean and renewable energy that the United Nations is concerned about. (American Austrian Titanium Nano Technology Co., Ltd.) At present, Yinlong has repeatedly made substantial progress in the field of energy storage. The U.S. Austrian Titanium Company, which is strategically controlled by Yinlong, also has a wealth of operation cases in the field of energy storage. The Austrian Titanium 1MW energy storage device and the 10.5MW wind power integration project of AES Company, and the El Salvador power grid stabilization system are lithium titanate ion. Batteries provide a reliable technical basis and operational data basis in the field of energy storage. The normal operation of multiple energy storage demonstration projects fully proves that my country's energy storage has completed the transition of the first three stages, namely basic research and development, application function verification, and function release, which have laid the foundation for commercialization.
