BYD's energy storage power station is located in Longgang District, Shenzhen, Guangdong Province, and is located in the Pearl River Delta region. It is used to cut peaks and fill valleys on the distribution network side. At the same time, it has auxiliary functions such as system standby, independent power supply, and reactive power compensation. The project is scheduled to start in September 2010 and completed in December 2010. After the project is completed, it will be connected to the Shenzhen Electric Network. Its main function is to shift the peaks and valleys, that is, to discharge at the peak load of the main transformer, and to charge at the low valley of the main transformer to increase the main transformer load rate and reduce the peaks and valleys. Poor purpose. The charging and discharging power of the energy storage station fluctuates with the change of the main transformer load, and aims to realize the intelligent control of the main transformer load.
All along, battery life, stability of charge and discharge power, and environmental adaptability are important factors that restrict the development of energy storage power plants. In the core technology field of energy storage carriers, BYD has developed the world's iron battery technology, which will increase the energy density of batteries to more than four times that of sealed lead-acid batteries. At the same time, the service life of the cycle will be as high as 7,000 times. 20 years of use. At the same time, the iron battery also has excellent environmental adaptability, and it can ensure stable discharge performance under high and low temperature and other harsh environments.
Like solar power plants and electric vehicles, energy storage power stations are among BYD's three major green dreams. The successful signing of the project indicates that the world's first commercial iron-battery MW-class energy storage power station will be born soon, and it also marks a new breakthrough in the global energy storage technology problem.
As the global power demand grows year by year, the load gap between peaks and troughs in electricity consumption is getting larger and larger. As a new emerging technology, battery storage power stations will bring revolutionary technological renewal to the grid energy storage domain, with enormous social effects. Economic Effects. Buffett emphasized that it was precisely because BYD's three dreams in the field of new energy, “electric cars, energy storage power stations, and solar power stations†impressed him. As a well-experienced investor in the world energy industry, Buffett’s Sino-U.S. energy has a very important position in the world energy sector. This also makes BYD’s cooperation with China Southern Power Grid in the energy field more exciting.
