Recently, Guangdong’s first energy storage demonstration project developed by Guangdong Energy Group Co., Ltd. at the Haiwanshi Wind Farm has been put into operation in Huilai County, Jieyang City.
This project has been put to the test since November 2022 and witnessed stable operation for over nine months. It plays a pivotal role in developing energy storage in Guangdong.
Zhang Xiangyu, an engineer of Guangdong Energy Group Science and Technology Research Institute Co., Ltd., introduced that the institute launched the “research and development of energy storage system technology” project in November 2020 and has carried out a series of research, including demonstration, design, development, and test.
The project has developed a 1 MW/1 MWh containerized battery energy storage system with safety and scalability, conducted innovative research in energy management, thermal management, and energy storage safety, and mastered the whole process of R&D technology and manufacturing of advanced wind and photovoltaic energy storage system.
According to Zhang, the project has developed a set of standardized battery modules with high-efficiency heat dissipation and temperature uniformity, which can control the temperature difference of the cell within 3℃ when air cooling, leading the industry. The project has developed a battery system with three layers of fire protection materials. It mitigates the risk of thermal runaway of the cells.
At present, the energy storage system has been connected to the wind farm in November 2022, effectively solving the problem of wind abandonment at the wind farm.
It is learned that Guangdong Energy Group Co., Ltd. plans to add 20 million kilowatts of new energy installed capacity by 2025 and strive for 30 million kilowatts. Based on the policies mandating energy storage allocation ratios ranging from 10% to 20%, with varying allocation durations of 2-4 hours issued by other provinces, the group’s new installed capacity of new energy storage will reach at least 4-6 GWh by 2025.
