The growth rate of grid energy storage demand will greatly benefit from lithium iron phosphate batteries. The growth in demand for energy storage from the grid has driven domestic demand for lithium iron phosphate batteries. At present, the domestic grid energy storage is still in the leading stage of the grid group. When it comes to selecting lithium battery suppliers, the domestic leading lithium iron phosphate battery company is its mainstream choice. New market breakthrough for lithium iron phosphate batteries-grid energy storage outbreak. According to research findings, in order to coordinate with the national power reform and grid groups to ease their own power supply pressure, the power transmission (distribution) side energy storage at the transformer end and the user side energy storage at the industrial and commercial end are the main The demand for grid energy storage projects in China has increased. According to multiple grid energy storage bidding and implementation projects this year, the application of energy storage systems supporting lithium iron phosphate batteries has become a mainstream choice for grid groups and operators. At present, the domestic lithium batteries used in energy storage are still dominated by lithium iron phosphate. This time, the domestic grid energy storage demand has exploded, which will directly drive the demand for lithium iron phosphate batteries. The main reasons are: first, the explosion of grid energy storage demand has provided a way to reduce production capacity for lithium iron phosphate batteries that cannot meet the new energy vehicle subsidy policy; second, with the recent years, power battery companies have improved technology and cost. Development, lithium iron phosphate batteries have cost-effective advantages compared to lead-acid and lead-carbon batteries. Grid energy storage is driving the demand for lithium iron phosphate batteries. At present, many lithium battery companies that have signed energy storage projects are constrained to start construction at the same time as power and energy storage capacity. Small and medium lithium battery companies in the industry are seeking OEM cooperation. . It is foreseeable that domestic grid energy storage will win a new market breakthrough for lithium iron phosphate batteries. In the past month, CATL, Lishen, Zhongtian Energy Storage, and Kelu have placed orders in the grid energy storage market, which has opened a new world for lithium iron phosphate batteries. Nowadays, lithium iron phosphate batteries have become the mainstream of domestic energy storage, especially grid energy storage applications, and energy storage will achieve a truly large-scale explosion in one or two market segments by 2020 at the latest. It is estimated that by 2020, the total demand for lithium energy storage on the power generation side and the grid side will be 8GWh. From the perspective of the overall energy storage application environment, lithium battery energy storage is mainly used in communication base stations, user-side peak shaving and valley filling, off-grid power stations, microgrids, rail transit, UPS, home energy storage, big data centers and other projects. However, combined with the main domestic environment, communication base stations leave less market space for lithium battery companies; UPS backup power has already been dominated by some lithium iron phosphate battery companies; domestic energy storage is subject to the electricity price mechanism, and land intensification is still blank. ; The big data center market is large, but it is still in the development stage. On the one hand, the power grid energy storage market is heating up to find a way out for overcapacity lithium iron phosphate batteries; on the other hand, lithium battery companies have improved technology, and lithium iron phosphate batteries can basically meet the auxiliary services of existing grid energy storage; at the same time, in recent years, Lithium battery companies cut costs, and the unit price of lithium iron phosphate batteries has fallen. From a long-term economic perspective, it has comparative advantages. Advantages of adopting lithium iron phosphate battery energy storage power station for peak shaving: 1. Using lithium iron phosphate battery as energy storage medium has the advantages of strong safety and reliability, high energy density, fast charge and discharge rate, and long service life; use SVG instead The traditional reactive power compensation device realizes instantaneous dynamic compensation of reactive power and harmonics by tracking the current in real time. 2. Adopting 'decentralized layout and centralized control3. The primary and secondary equipment are highly integrated, and the standard prefabricated cabin layout is adopted to realize modularization of design schemes, universal equipment foundation, standardization of construction and construction, shorten construction period, and save construction costs. 4. The energy storage power station is connected to the source network load system, and the ability of the energy storage equipment to quickly transform the operating state is realized to realize the millisecond transformation of the energy storage equipment from 'load' to 'power sourceSystem' to lay the foundation. 5. Optimize the electrical main wiring, optimize the form of one-to-one correspondence between the incoming cabinet and the PCS cabin as 'one tow four, one tow three, Effectively reduce the floor area. At present, lithium iron phosphate batteries have become the mainstream of domestic energy storage applications, especially grid energy storage applications. According to multiple grid energy storage bidding and implementation projects this year, the application of lithium battery supporting energy storage systems has become the mainstay of grid groups and operators. Mainstream choice. Compared with lead-acid and lead-carbon batteries, lithium iron phosphate batteries have cost-effective advantages.
