Specific introduction to the main application areas of lithium iron phosphate batteries

With the rise of the energy storage market, in recent years, some power battery companies have laid out their energy storage business to explore new application markets for lithium iron phosphate batteries. On the one hand, due to its ultra long lifespan, safe use, large capacity, and green environmental protection, lithium iron phosphate can be transferred to the energy storage field, which will prolong the value chain and promote the establishment of a new business model. On the other hand, energy storage systems for lithium iron phosphate batteries have become the mainstream choice in the market. According to reports, lithium iron phosphate batteries have been attempted for frequency regulation on electric buses, electric trucks, user side, and grid side.
(1) Safe grid connection of renewable energy generation such as wind power and photovoltaic power. The inherent randomness, intermittency, and volatility of wind power generation determine that its large-scale development will inevitably have a significant impact on the safe operation of the power system. With the rapid development of the wind power industry, especially in China where most wind farms belong to large-scale centralized development and long-distance transmission, the grid connected power generation of large wind farms poses a serious challenge to the operation and control of the large power grid.
Photovoltaic power generation is influenced by environmental temperature, sunlight intensity, and weather conditions, and exhibits a random fluctuation characteristic. China is showing a development trend of "decentralized development, low voltage on-site access" and "large-scale development, medium and high voltage access", which puts higher requirements on grid peak shaving and safe operation of the power system.
Therefore, high-capacity energy storage products have become a key factor in solving the contradiction between the power grid and renewable energy generation. The lithium iron phosphate battery energy storage system has the characteristics of fast working condition conversion, flexible operation mode, high efficiency, safety and environmental protection, and strong scalability. It has been applied in the national wind and solar energy storage and transmission demonstration project, which will effectively improve equipment efficiency, solve local voltage control problems, improve the reliability of renewable energy generation, and improve power quality, making renewable energy a continuous and stable power supply.
With the continuous expansion of capacity and scale, and the continuous maturity of integrated technology, the cost of energy storage systems will be further reduced. After safety and reliability testing, lithium iron phosphate battery energy storage systems are expected to be widely used in the safe grid connection and improvement of energy quality of renewable energy generation such as wind power and photovoltaic power.
(2) Peak shaving of the power grid. The main means of peak load regulation in the power grid has always been pumped storage power stations. Due to the need to build two reservoirs, the upper and lower, for pumped storage power stations, which are greatly limited by geographical conditions, it is not easy to build in plain areas, and the land area is large, resulting in high maintenance costs. The use of lithium iron phosphate battery energy storage systems to replace pumped storage power stations can cope with peak loads in the power grid, without being limited by geographical conditions, with free site selection, less investment, less land occupation, and low maintenance costs. It will play an important role in the peak shaving process of the power grid.
(3) Distributed power plants. The inherent defects of large power grids make it difficult to ensure the quality, efficiency, safety, and reliability requirements of power supply. For important units and enterprises, dual or even multiple power sources are often needed as backup and protection. The lithium iron phosphate battery energy storage system can reduce or avoid power outages caused by power grid failures and various unexpected events, ensuring the safety of hospitals, banks, command and control centers, and data processing
